BananaPi M4 Zero: enable 8821cu and blacklist rtw88_8821cu (#6365)

rtw88_8821cu takes priority over the github driver, so this
shouldn't effect other units or usb dongles people use.

My reasoning is; The rtw88 driver for reasons yet unknown seems
to trigger usb fails more often than the github driver. If a
fail occurs it will introduce dmesg spam and upon reboot leave
the onboard wireless module undetectable.
