Add QCA vendor command and attributes for RROP

Add QCA vendor command and attributes for vendor specific Representative
RF Operating Parameter (RROP) information. This information is intended
for optional use by external ACS. It provides guidance values for some
RF parameters that are used by the system during operation, so that
external ACS can utilize these to compare between channels, bands, etc.
