From: Ilan Peer <ilan.peer@intel.com>

Add configuration options for setting the Tx Power value
in the Transmit Power Envelope for 6GHz:

- The Tx power value for default client where the transmit
  power interpretation is "Regulatory Client EIRP PSD"
- The Tx power value for subordinate client where the transmit
  power interpretation is "Regulatory Client EIRP PSD"
