OPP: Migrate set-supported-hw API to use set-config helpers
Now that we have a central API to handle all OPP table configurations,
migrate the set-supported-hw family of helpers to use the new
infrastructure.
The return type and parameter to the APIs change a bit due to this,
update the current users as well in the same commit in order to avoid
breaking builds.
