34df003519 gpu: nvgpu: using pmu counters for load estimate
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.

94e00ab6ad gpu: nvgpu: gk20a: fix MISRA 10.4 Violations [1/2]
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.
