Subject: [PATCH v4 2/6] PM / devfreq: Switch to dev_pm_opp_find_freq_{ceil/floor}_indexed() APIs
Some devfreq consumers like UFS driver need to work with multiple clocks
through the OPP framework. For this reason, OPP framework exposes the
_indexed() APIs for finding the floor/ceil of the supplied frequency of
the indexed clock. So let's use them in the devfreq driver.
Currently, the clock index of 0 is used which works fine for multiple as
well as single clock.
