If the GPIO controllers are so different, should they not have different
compatible strings?

Maybe add rda,8810pl-modem-gpio compatible for the modem
GPIO then?

Then this can be conditional using an if:-statement such that
it is only mandatory for rda,8810pl-gpio and not for
rda,8810pl-modem-gpio.
