OPP: Introduce dev_pm_opp_find_freq_{ceil/floor}_indexed() APIs
In the case of devices with multiple clocks, drivers need to specify the
clock index for the OPP framework to find the OPP corresponding to the
floor/ceil of the supplied frequency. So let's introduce the two new APIs
accepting the clock index as an argument.
These APIs use the exising _find_key_ceil() helper by supplying the clock
index to it.
