wifi: rtl8xxxu: Support new chip RTL8192FU 

This is a newer chip, similar to the RTL8710BU in that it uses the same
PHY status structs.

Features: 2.4 GHz, b/g/n mode, 2T2R, 300 Mbps.

It can allegedly have Bluetooth, but that's not implemented here.

This chip can have many RFE (RF front end) types, of which types 1
and 5 are the only ones tested. Many of the other types need different
initialisation tables. They can be added if someone wants them.

The vendor driver v5.8.6.2_35538.20191028_COEX20190910-0d02 from
https://github.com/BrightX/rtl8192fu was used as reference, with
additional device IDs taken from
https://github.com/kelebek333/rtl8192fu-dkms

.

The vendor driver also claims to support devices with ID 0bda:a725,
but that is found in some bluetooth-only devices, so it's not supported
here.
