[4/4] clk: qcom: gcc-msm8916: Add power domain data

Commit Message

Jun Nie Aug. 5, 2022, 7:49 a.m. UTC 
Add power domain performance state and ceiling freq mapping table
so that optimal performance point can be voted by clks within
clock controller. This is not related to the clks consumer devices.

Run this command to check genpd perf state:
cat /sys/kernel/debug/pm_genpd/vddcx/perf_state
