utf_falcons in libfalcon_utf.so are used by multiple unit tests and
since unit tests are run out of order it might lead to inconsistent
access to these structs.
Move these to falcon unit test. Updated the logic in the falcon utf
shared library to only export the interfaces to read/write to flcn
registers/memory.

Rule 2.2 doesn't allow unused variable assignments. The reason is
presence of unused variable assignments may indicate error in program's
logic.
Rule 7.2 requires all unsigned numeric literals to use a "u"/"U" suffix.

names and type qualifier.

Rule 12.2 requires right hand operand of shift operator to be within

Once CONFIG_NVGPU_RECOVERY is permanently disabled for safety build,
we can remove those functions from the export file.
Until we can disable it, make sure that related functions do exist,
even when CONFIG_NVGPU_RECOVERY is disabled, by using #ifdefs inside
the functions, instead of redeclaring functions as static inline.

As a part of safety check, golden context is created twice
(back to back) and two golden context images are compared.
These two images should be identical for safety check.
Currently there is one hw deviation happening because of stats
counter idle clock increments. To avoid this, stats counter
clocks enable is disabled. To have a valid golden context(
avoid mismatch between fe and mpc), original stats counter
bundle is programmed through mme shadow register.
Before first golden context save, golden image is saved in
a local copy. Same copy is restored back after first golden
save. Second golden context save is done with this local copy
and two golden contexts are compared.
