BananaPi CM4: improve SDIO WiFi speeds

Browse Source 
Improve overall WiFi experience
Default freq now set to 100MHz (optional overlay to 200MHz)
Resolved incompatibility with the github driver: https://github.com/jethome-ru/rtl88x2cs

If the github driver is preferred blacklist RTW88

/etc/modprobe.d/blacklist-rtw88.conf
blacklist rtw88_8822c
blacklist rtw88_8822cs

EXTRA: Waveshare DTS fixup
