rtw88: 8723d: implement set_tx_power_index ops
The txagc table is used to map rate_id and txagc register address and mask, and ops set_tx_power_index uses this table to write TX power to corresponding registers. Since 8723D is a 1x1 2.4G 11n chip, only CCK, OFDM and HT_MCS 0-7 are listed in the table.
