Daniele Ceraolo Spurio 561055b810 drm/i915/mtl/gsc: Add a gsc_info debugfs 
Add a new debugfs to dump information about the GSC. This includes:

- the FW path and SW tracking status;
- the release, security and compatibility versions;
- the HECI1 status registers.

Note that those are the same registers that the mei driver dumps in
their own status sysfs on DG2 (where mei owns the GSC).

To make it simpler to loop through the status register, the code has
been update to use a PICK macro and the existing code using the regs had
been adapted to match.

v2: fix includes and copyright dates (Alan)
v3: actually fix the includes

# Direct Rendering Infrastructure (DRI) in XFree86 4.1.0 and higher.
# Add a set of useful warning flags and enable -Werror for CI to prevent
# trivial mistakes from creeping in. We have to do this piecemeal as we reject
# any patch that isn't warning clean, so turning on -Wall -Wextra (or W=1) we
# need to filter out dubious warnings. Still it is our interest
# to keep running locally with W=1 C=1 until we are completely clean.

# Note the danger in using -Wall -Wextra is that when CI updates gcc we
# will most likely get a sudden build breakage... Hopefully we will fix
# new warnings before CI updates!
