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.

PMU falcon base address was being set without invoking hal api. Remove
FALCON_PWR_BASE. This patch defines gpu_ops.pmu.falcon_base_addr hal api
to get this base address.

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.

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.
Adding "U" at the end of the integer literals to have same type of
operands when an arithmetic operation is performed.
This fixes violation where an arithmetic operation is performed on
signed and unsigned int types.
