Runlist update occurs in non-mission mode, when
adding/removing channel/TSGs. The pending bit
is a debug only feature. As a result logging a
warning is sufficient.
We expect other HW safety mechanisms such as
PBDMA timeout to detect issues that caused pending
to not clear. It's possible bad base address could
cause some MMU faults too.
Worst case we rely on the application level task
monitor to detect the GPU tasks are not completing
on time.

Removed BUG_ON statements from gm20b_pbdma_acquire_val, as
condition could never be true. The only overflow that can
happen is in nvgpu_safe_mult_u64.
Compute exponent by shifting timeout (in units of 1024 ns)
until it fits into mantissa. This removes the need to
compute most significant bits, and allows using hw definitions
for mantissa and exponent max values.

Add unit tests to cover the invalid falcon port access, falcon sw init
switch cases, nvgpu_falcon_set_irq, nvgpu_timeout_init failure branch
coverage.
Compile out the functions nvgpu_falcon_get_mem_size & falcon_bootstrap
as they are needed by LS PMU and VBIOS code. For iGPU safety the
falcon functions needing these will call the HAL APIs directly.
This way we avoid the unreachable code as well. Updated the
prototype of falcon bootstrap HAL API as that doesn't return
any error.
With these changes, we get 100% line coverage for common.falcon unit.

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.

Split GR ECC initialization into GPC/TPC and FECS ECC init as FECS ECC
errors during acr_construct_execute need to be reported and handled
hence FECS ECC counters are required to be initialized before
acr_construct_execute.
GPC/TPC ECC counters are dependent on the GR config that will be
initialized only after acr_construct_execute.
nvgpu_gr_intr_init_support is moved to nvgpu_gr_prepare_sw.
FECS ECC interrupt is enabled by default hence interrupt is not
enabled through gr_fecs_host_int_enable_r in nvgpu_gr_prepare_sw.
