57f3968cb9 gpu: nvgpu: mc: address code inspection gaps
Address following issues uncovered during inspection:
1. Remove the doxygen comment from nvgpu_wait_for_deferred_interrupts
   definition.
2. Use NVGPU_MC_INTR_STALLING instead of hardcoding the index.
3. Define doxygen groups NVGPU_MC_UNIT_ENUMS,
   NVGPU_MC_INTR_TYPE_DEFINES, NVGPU_MC_INTR_UNIT_DEFINES and
   NVGPU_MC_INTR_ENABLE_DEFINES.
4. Update the doxygen comments.
5. Fix the cleanup, typo in the description of the test
   test_wait_for_deferred_interrupts.

It was observed that some of the informational debug prints in the
LTC ISRs were printed through nvgpu_err. They should be instead
printed through nvgpu_log under flag gpu_dbg_intr.

66b68edd6b gpu: nvgpu: iterator name for active_engines
Some functions used engine_id or eng_id to index active_engines_list,
which could get confusing when used in conjunction with similar
variable as active_engine_id or act_eng_id.

Use generic iterator name i or j instead, to make it clear that
f->active_engines_list is NOT indexed by engine id.

fba516ffae gpu: nvgpu: enable PMU ECC interrupt early
PMU IRQs were not enabled assuming entire functionality for LS PMU.
Debugging early init issues of PMU falcon ECC errors triggered
during nvgpu power-on will be cumbersome if interrupts are not
enabled early. FMEA analysis of the nvgpu init path also
requires this interrupt be enabled earlier.

Hence, Enable the PMU ECC IRQ early during nvgpu_finalize_poweron.
pmu_enable_irq is updated to enable interrupts differently for
safety and non-safety. PMU interrupts disabling is moved out
of nvgpu_pmu_destroy to nvgpu_prepare_poweroff. Prepared new
wrapper API nvgpu_pmu_enable_irq.

PMU ECC init and isr mutex init is moved to the beginning of
nvgpu_pmu_early_init as for safety, ls pmu code path is
disabled. Fixed the pmu_early_init dependent and mc
interrupt related unit tests.

Update the doxygen for changed functions.

a8c9c800cd gpu: nvgpu: reorganization of MC interrupts control
Previously, unit interrupt enabling/disabling and corresponding MC level
interrupt enabling/disabling was not done at the same time.
With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.

For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.
