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
