To support TX diversity, query firmware to know if it is 1T2R variant
model. Then, checking RSSI periodically to know which antenna has better
signal strength that can be seen as the antenna is close to AP. Therefore,
use the antenna with better RSSI to transmit packets dynamically.

v3:
  - patch 3/5: just 'return ret' instead of overwriting error code.

v2:
  - patch 3/5: use separate 'ret'
  - patch 5/5: no need casting from void pointer

Ping-Ke Shih (5):
  wifi: rtw89: use u32_get_bits to access C2H content of PHY capability
  wifi: rtw89: parse phycap of TX/RX antenna number
  wifi: rtw89: configure TX path via H2C command
  wifi: rtw89: record signal strength per RF path
  wifi: rtw89: support TX diversity for 1T2R chipset
