drm/msm/dpu: Use OPP API to set clk/perf state

Browse source

On some qualcomm platforms DPU needs to express a performance state
requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.
