OPP: Introduce dev_pm_opp_find_freq_ceil_by_volt()
This patch introduces a new helper routine in the OPP core, which
returns the OPP with the highest frequency which has voltage less than
or equal to the target voltage passed to the helper.

[ Viresh: Massaged the commit log and renamed the helper with some
cleanups. ]
