Add DRV config blob handling for programming required registers per request. Also, add debugfs entry for disabling DRV feature from ife hw manager. Update existing BW voting logs to reflect DRV vote level info. Add support for communicating with rsc device upon update in MNOC BW. Also, update BW voting logic in cpas to accommodate DRV voting to interconnect framework.
