MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch changes pmu_elpg_statistics to return a status based
on the result of nvgpu_falcon_copy_from_dmem and propagate it upstream.

Currently, PMU f/w ucode read is part of ACR prepare ucode blob
which makes PMU to depend on ACR to init PMU f/w version related
ops & to include PMU related members to be part of ACR data struct
to free the allocated space for PMU ucodes.
Moved PMU f/w ucode read to PMU early init function & initializing
version ops once PMU ucode descriptor is available.

PMU counters #0 and #4 are used to count total cycles and busy cycles.
These counts are used by podgov to estimate GPU load.
PMU idle intr status register is used to monitor overflow. Overflow
rarely occurs because frequency governor reads and resets the counters
at a high cadence. When overflow occurs, 100% work load is reported to
frequency governor.

The function nvgpu_pmu_cmd_post() included a timeout parameter, but all
callers were just passing the max value, so it was useless. This change
removes that parameter from that function. The same was true for
therm_pmu_cmd_post() that calls nvgpu_pmu_cmd_post(), so do the same to
it.

This change fixes a number of This is a MISRA 10.3 rule violation due to
the implicit casts of sizeof() to u32's. This change adds u32 casts to
each of these violations. This should be safe because a 4GB type size
would be very unlikely in this driver.
