Modified PMU subunits init sequence as they required during PMU RTOS
initialize stage, function nvgpu_pmu_early_init() allocates space for
all its subunit & its default values for further usage during runtime,
and function nvgpu_pmu_init() performs setup for sub units & starts
PMU-RTOS boot.
Deinit of all sub units allocated space will handled as part of
remove_support stage & also, during init stage upon failure of
init/setup sequence.

MISRA Rule 11.2 doesn't allow conversion to or from an incomplete type
pointer, as it may result incorrect point alignment and may further lead
to undefined behavior.
MISRA Rule 16.x requires all switch statements to be well-formed with
terminating break statement for every switch-clause.
This patch fixes 11.2 and 16.x violations in common.mm.nvgpu_mem.

of the read pointer (MAILBOX1).
- The ucode will check if the feature is enabled/disabled
before writing a record into the circular buffer. If the
feature is disabled, it will not write the record.
- If the feature is enabled and the buffer is not allocated,

MISRA Rule 14.2 requires for loop to be well-formed. A well-formed for
loop has below requirements:
1. first clause can be empty or should assign value to a single loop
counter
2. second clause should exist and use loop counter or loop control flag.
It should not use any variable modified in the loop body.
3. third cluase should only update loop counter and should not use
objects modified in the loop body.
This modifies for loops to process single loop counter. The patch moves
additional initializations before for loop, conditions at loop start
and variable updates at the end of for loop.
