drm/msm/dp: "inline" dp_ctrl_set_clock_rate("ctrl_link")

Browse Source 
"ctrl_link" is the clock from DP_CTRL_PM module. The result of setting
the rate for it would be a call to dev_pm_opp_set_rate(). Instead of
saving the rate inside struct dss_module_power, call the
devm_pm_opp_set_rate() directly.
