9e2f028317 gpu: nvgpu: fix MISRA 17.7 falcon_copy_from_dmem
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 a call to falcon_copy_from_dmem to handle
error codes.

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.

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.

In nvgpu repository, we have multiple accesses to methods in
pmu_gk20a.h which have register accesses. Instead of directly invoking
these methods, these are now called via HALs. Some common methods such
as pmu_wait_message_cond which donot have any register accesses
are moved to pmu_ipc.c and the method declarations are moved
to pmu.h. Also, changed gm20b_pmu_dbg to
nvgpu_dbg_pmu all across the code base. This would remove all
indirect dependencies via gk20a.h into pmu_gk20a.h. As a result
pmu_gk20a.h is now removed from gk20a.h
