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.
