Currently, msm_drv was creating dpu_power_handle client
which was used by dpu_dbg module to enable power resources
before register debug dumping.
Now since, the mdss core power resource handling is
implemented via runtime_pm and same has been removed
from dpu_power_handle. Remove dpu_power_handle dependency
from msm_drv and use pm_runtime_get/put_sync calls from
dpu_dbg module on dpu_mdss top level device for core,
ahb clock and power resource management (for register access).
Changes in v2:
- resolved conflict in dpu_core_perf_init
- dropped (Reviewed-by: Sean Paul) due to above change
