qcacmn: Add an API to get max TxPower for 6G TPE

Selaa lähdekoodia 
Add an API wlan_reg_get_max_txpower_for_6g_tpe, to get the max tx-power
in PSD or EIRP format, based on the client type as follows:

 =======|===============================================
| S No. |      Default Client       | Subordinate Client|
|=======|===============================================|
| EIRP  | reg_get_channel_reg_power |       24 dBm      |
|       | _for_freq(pdev, freq)     |                   |
|-------------------------------------------------------|
| PSD   |          (-1) dBm         |        5 dBm      |
 =======================================================
