Add a ceil version of the dev_pm_opp_find_level(). It's handy to have if levels don't start from 0 in OPP table and zero usually means a minimal level.

Why doesn't the exact version work for you here ?
The exact version won't find OPP for level=0 if levels don't start with 0, where 0 means that minimal level is desired.
Right, but why do you need to send 0 for your platform ?
To put power domain into the lowest performance state when device is idling.
