gpu: nvgpu: invoke calls to methods in pmu_gk20a.h via HAL

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
