6 GHz regulatory domain introduces different power modes for 6 GHz AP operation - Low Power Indoor(LPI), Standard Power(SP) and Very Low Power(VLP). 6 GHz STAs could be operated as either Regular or Subordinate clients. We have separate definitions of AP and client. However, during concurrency (multi-interfaces), it would be difficult to keep different enum containers for different interface types in order to track its power mode. Add new combined power type definition for 6 GHz interfaces. Also add support to convert existing AP/Client Power type to this new combined power type enum.
