wifi: rtw89: set capability of TX antenna diversity
TX antenna diversity is a mechanism to select a proper antenna from two
antenna for single one hardware PHY chip. It chooses antenna with better
EVM or RSSI, and use GPIO to control SPDT to switch selected antenna.
RFE type from efuse is used to define if a module can support TX antenna
diversity when (type % 3) is 2.
