Enable using a fractional (compressed) link bpp on MST links, if this is
supported and the link bpp is forced. Fractional link bpps will be
enabled by default as a follow-up change after testing this
functionality within a set of commonly used MST monitors and docks/hubs
which support it.

Add support for forcing the link bpp on a connector via a connector
debugfs entry. During reducing link bpps due to a link BW limit, keep
bpps close to their forced value.
Add the debugfs entry to all relevant connectors: all DP connectors and
on an FDI link CRT/SDVO/LVDS/HDMI connectors.
v2:
- Move adding the debugfs entries to this patch.
- Rename i915_force_link_bpp to intel_force_link_bpp. (Jani)
- Select the relevant connectors via platform checks. (Jani)
- Use for_each_new_intel_connector_in_state(). (Jani)
- Fix 64 bit division vs. 32 bit build when converting str to q4. (lkp)
- Avoid division and addition overflow when converting str to q4.
v3:
- Add TODO: to make the non-DSC min bpp value connector specific. (Ankit)

Add support for a fractional compressed link bpp on an MST link. Leave
the actual enabling of fractional bpps to a follow-up change.
While at it add an assert before the bpp loop, that the min and max bpps
are aligned to the bpp step. This should hold regardless of the non-DSC/DSC
or MST/UHBR-SST modes.
This keeps the mode validation and DSC->DPT BW specific maximum link
bpps as rounded-down integer values still, changing those to a
fractional value is left for later, add here TODO comments for them.
v2:
- Align the min/max bpp value to the bpp step.
- Assert that the min/max bpp values are aligned to the bpp step.

Adjusting the compressed bpp range min/max limits in
intel_dp_dsc_nearest_valid_bpp() is unnecessary:
- The source/sink min/max values are enforced already by the
link_config_limits::min_bpp_x16/max_bpp_x16 values computed early in
intel_dp_compute_config_link_bpp_limits().
- The fixed set of valid bpps are enforced already - for all bpps in the
min .. max range by intel_dp_dsc_valid_compressed_bpp() called from
intel_dp_mtp_tu_compute_config().
The only thing needed is limiting max compressed bpp below the
uncompressed pipe bpp, do that one thing only instead of calling
intel_dp_dsc_nearest_valid_bpp().

Check the BW requirement of a selected compressed bpp against the total
MST link BW early. This didn't cause a problem, since all the BW limits
within the MST topology are checked during the later MST topology BW
check. However it doesn't make sense to defer the total link BW check,
since for resolving a BW limit issue due to this later also (a) requires
selecting a pipe to reduce its bpp, ending up reducing the bpp for
another pipe, which is not ideal (b) requires recomputing the state for
all CRTC/stream's in the topology which may slow down the commit
considerably (especially when using fractional bpps).
Based on the above, check a stream bpp's BW requirement against the MST
link's total BW early.
Ideally drm_dp_atomic_find_time_slots() should check internally the
corresponding PBN/TU slot BW against the total link BW, returning an
error if the check fails, however that change would also affect other
drivers, so leaving this for a follow-up.

A follow up change will check a selected bpp's BW requirement in
intel_dp_mtp_tu_compute_config(), however that requires the total link
slot count to be up-to-date. The latter in turn depends on the channel
encoding and hence the link rate used, so it can be set after the
link rate used is selected.
This also allows simplifying mst_stream_update_slots(), do that as well,
moving the function definition before its use.

Atm TGL supports only a fixed set of valid DSC compressed bpps
(6,8,10,12,15), but this is not taken into account while looking for a
bpp in the minimum..maximum compressed bpp range.
This happened to work only by chance since atm from the above min..max
range it's always the maximum bpp that is selected, which is one of the
above valid bpps (see mst_stream_dsc_compute_link_config() ->
intel_dp_dsc_nearest_valid_bpp()). Before selecting a bpp however, the
bpp's BW requirement should be checked wrt. to the MST total link BW;
after doing that - in a follow-up change - the validity of any bpp in
the min..max range must be ensured before the bpp is selected, do that
here.

limit on MST
Atm, on an MST link in DSC mode
intel_dp_compute_config_link_bpp_limits() calculates the maximum link
bpp limit using the MST root connector's DSC capabilities. That's not
correct in general: the decompression could be performed by a branch
device downstream of the root branch device or the sink itself.
Fix the above by passing to intel_dp_compute_config_link_bpp_limits()
the actual connector being modeset, containing the correct DSC
capabilities.

In preparation for making the kmalloc family of allocators type aware,

the type of the variable being assigned. (Before, the allocator would
always return "void *", which can be implicitly cast to any pointer type.)
The assigned type is "struct i915_wa *". The returned type, while
technically matching, will be const qualified. As there is no general
way to remove const qualifiers, adjust the allocation type to match

Observe that i915->irq_lock is no longer used to protect anything
outside of display. Make it a display thing.
This allows us to remove the ugly #define irq_lock irq.lock hack from xe
compat header.
Note that this is slightly more subtle than it first looks. For i915,
there's no functional change here. The lock is moved. However, for xe,
we'll now have *two* locks, xe->irq.lock and display->irq.lock. These
should protect different things, though. Indeed, nesting in the past
would've lead to a deadlock because they were the same lock.
With the i915 references gone, we can make a handful more files
independent of i915_drv.h.

As seen in some recent failures, SLPC num_waiters value is < 0.
This happens because the inc/dec are not balanced. We should skip
decrement for the same conditions as the increment. Currently, we
do that for power saving profile mode. This patch also ensures that
num_waiters is incremented in the case min_softlimit is at boost
freq. It ensures that we don't reduce the frequency while this request
is in flight.

Display driver handles the need to program the fbc stride using
the override stride. So ensure that we always get the override
stride in case of bmg
