Subject[PATCH] of: Don't create platform device for OPP tables
Date
The OPP tables are present as separate nodes, whose phandle is used in
the "operating-points-v2" property of devices. Currently the OF core
creates a platform device for the OPP table unconditionally, which is
not used by any kernel code.

Skip creating OPP table platform devices.
