-EIO has special meaning and is used when we want to allow
engine initialization to fail and mark GPU as wedged.
However here at this function we should return error code
that corresponds to upload status only, as any decision how
to handle missing firmware should be done higher level function
(silent fallback to non-GuC mode, fail into wedged mode, or
abort driver load with fatal error).

We should be consistent on naming of similar definitions.

Include GuC and HuC firmware details in captured error state
to provide additional debug information. To reuse existing
uc firmware pretty printer, introduce new drm-printer variant
that works with our i915_error_state_buf output. Also update
uc firmware pretty printer to accept const input.
v2: don't rely on current caps (Chris)
dump correct fw info (Michal)
v3: simplify capture of custom paths (Chris)
v4: improve 'why' comment (Joonas)
trim output if no fw path (Michal)
group code around uc error state (Michal)
v5: use error in cleanup_uc (Michal)

Debugfs for GuC and HuC load info have similar common part.
Move and update dump of uc_fw to separate helper for reuse.

Firmware loading for GuC and HuC are similar. Move common code
into generic function for maximum reuse.

In case of firmware fetch failure we should help user
find latest firmware. URL macro duplication from csr.c
will be fixed in upcoming patch.

Both GuC and HuC firmwares will be moved into WOPCM so
we can check ucode size early for both cases.
