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.

into generic function for maximum reuse.

Some of the error messages from DMC load were too generic and
may be confusing for the user. Lets explicitly add DMC words there.
Also as homepage of DMC firmware is same as for the GuC and Huc,
lets reuse URL definition.

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.

With the code motion mostly done, convert all the uC code away
from uint??_t at once (only a couple dozen variables), so that
reading the checkpatch.pl output should actually pinpoint if
a new uint??_t was accidentally introduced.
