wifi: rtw89: 8922a: update chip parameter for coex

Implement the chip operation function for 8922a, it related to TX power,
RX gain, antenna position, packet priority and so on. Also assign
coexistence priority table for hardware PTA using. Add settings to avoid
uncertainties propagation when Wi-Fi Rx due to RF gain mismatch.
