It is incorrect to use devm-managed memory allocations for DRM data
structures exposed to userspace. They should use drmm_ allocations.
Change struct dpu_encoder allocation to use drmm_encoder_alloc(). This
removes the need to perform any actions on encoder destruction.

Some users need to release resources attached to the vm_bo object when
it's destroyed. In Panthor's case, we need to release the pin ref so
BO pages can be returned to the system when all GPU mappings are gone.
This could be done through a custom drm_gpuvm::vm_bo_free() hook, but
this has all sort of locking implications that would force us to expose
a drm_gem_shmem_unpin_locked() helper, not to mention the fact that
having a ::vm_bo_free() implementation without a ::vm_bo_alloc() one
seems odd. So let's keep things simple, and extend drm_gpuvm_bo_put()
to report when the object is destroyed.

To make sure that we don't unintentionally perform any unclocked and/or
unpowered R/W operation on GPU registers, before turning off clocks and
regulators we must make sure that no GPU, JOB or MMU ISR execution is
pending: doing that requires to add a mechanism to synchronize the
interrupts on suspend.
Add functions panfrost_{gpu,job,mmu}_suspend_irq() which will perform
interrupts masking and ISR execution synchronization, and then call
those in the panfrost_device_runtime_suspend() handler in the exact
sequence of job (may require mmu!) -> mmu -> gpu.
As a side note, JOB and MMU suspend_irq functions needed some special
treatment: as their interrupt handlers will unmask interrupts, it was
necessary to add an `is_suspended` bitmap which is used to address the
possible corner case of unintentional IRQ unmasking because of ISR
execution after a call to synchronize_irq().
At resume, clear each is_suspended bit in the reset path of JOB/MMU
to allow unmasking the interrupts.

Some SoCs may be equipped with a GPU containing two core groups
and this is exactly the case of Samsung's Exynos 5422 featuring
an ARM Mali-T628 MP6 GPU: the support for this GPU in Panfrost
is partial, as this driver currently supports using only one
core group and that's reflected on all parts of it, including
the power on (and power off, previously to this patch) function.
The issue with this is that even though executing the soft reset
operation should power off all cores unconditionally, on at least
one platform we're seeing a crash that seems to be happening due
to an interrupt firing which may be because we are calling power
transition only on the first core group, leaving the second one
unchanged, or because ISR execution was pending before entering
the panfrost_gpu_power_off() function and executed after powering
off the GPU cores, or all of the above.
Finally, solve this by:
- Avoid to enable the power transition interrupt on reset; and
- Ignoring the core_mask and ask the GPU to poweroff both core groups

typical values and it's not clear if they are no min and max values or
if you must use the typical value exactly. To make things worse, there
is no back porch but only a combined sync and back porch length.
Unfortunately, there is not public datasheet. Therefore, here are the
relevant timings:

Apart from the already handled data bus (MAS_MDP_Pn<->DDR), there's
another path that needs to be handled to ensure MDSS functions properly,
namely the "reg bus", a.k.a the CPU-MDSS interconnect.
Gating that path may have a variety of effects, from none to otherwise
inexplicable DSI timeouts.
Provide a way for MDSS driver to vote on this bus.
A note regarding vote values. Newer platforms have corresponding
bandwidth values in the vendor DT files. For the older platforms there
was a static vote in the mdss_mdp and rotator drivers. I choose to be
conservative here and choose this value as a default.

There are just two places where we set the bandwidth: in the resume and
in the suspend paths. Drop the wrapping function
msm_mdss_icc_request_bw() and call icc_set_bw() directly.

The DPU1 driver needs to handle all MDPn<->DDR paths, as well as
CPU<->SLAVE_DISPLAY_CFG. The former ones share how their values are
calculated, but the latter one has static predefines spanning all SoCs.
In preparation for supporting the CPU<->SLAVE_DISPLAY_CFG path, rename
the path-related struct members to include "mdp_".

Stop using hand-written reset function for ICC release, use
