From: John Harrison <John.C.Harrison@Intel.com>

Enhance the firmware table verification code to catch more potential
errors and to generally improve the code itself.

Track patch level version even on reduced version files to allow user
notification of missing bug fixes.

Detect another immediate failure case when loading GuC firmware.

Treat more problems as fatal errors, at least for DEBUG builds.

v2: Use correct patch version number, drop redundant debug print
fail load on table validation error (review by Daniele / CI results).
v3: Fix spelling typos, use a new bool for invalid firmware tables
rather than a status enum (review feedback from Daniele).
