rtw89: 8852c: implement chip_ops related to TX power
Three chip_ops are implemented in this patch. The ::set_txpwr_ctrl and
::init_txpwr_unit are called when we up interface and then configure TX
power registers to initial values. The ::set_txpwr_ctrl is to configure
'txpwr_ref' to make basic output TX power of OFDM and CCK rate to be the
same. The ::init_txpwr_unit is to initialize TSSI (a method to do TX power
compensation depends on thermal value) control and bandedge.
The ::set_txpwr is called once switching channel. First, it sets TX power
for each rate section (e.g. CCK, OFDM), and then sets TX power offset
between 1SS and 2SS rate. Finally, it sets TX power limit to prevent
power over regulation.
