OPP: Move required opps configuration to specialized callback
The required-opps configuration is closely tied to genpd and performance
states at the moment and it is not very obvious that required-opps can
live without genpds. Though we don't support configuring required-opps
for non-genpd cases currently.
This commit aims at separating these parts, where configuring genpds
would be a special case of configuring the required-opps.
Add a specialized callback, set_required_opps(), to the opp table and
set it to different callbacks accordingly.
This shouldn't result in any functional changes for now.
