wifi: rtw89: 8852b: add functions to control BB to assist RF calibrations

When we are going to do RF calibrations, they need BB helpers to control
TX PLCP, power, path and mode. Also, it they need helpers to backup and
restore some registers before and after RF calibrations. Then, use flow of
RF calibrations will be like backup registers, configure calibration,
configure TX parameters, measure calibration result, and finally restore
registers.

wifi: rtw89: 8852b: add chip_ops to configure TX/RX path

To support variant models, such as 1x1 or 1T2R, we need this chip_ops to
change the path accordingly.

wifi: rtw89: 8852be: add 8852BE PCI entry

8852BE has two variants with different ID. One is 10ec:b852 that is a main
model with 2x2 antenna, and the other is 10ec:b85b that is a 1x1 model.

wifi: rtw89: 8852b: add chip_ops to read efuse

efuse stores individual data about a chip itself, such as MAC address,
country code, RF and crystal calibration data, and so on. Define a struct
to help access efuse content, and copy them into a common struct.

wifi: rtw89: 8852b: add chip_ops::set_txpwr

This chip_ops is to set TX power according to country, channel, rate and
so on. Since shared code is used to configure TX power, we only implement
specific part in this patch.
