As noted in the cover message, this is to highlight the issue to
hopefully get folk to think what we should do about RMII and REVMII
in this driver - basically, should we continue to support them, or
remove it completely.

Either way, this patch won't hit net-next in its current form.

Essentially, the choice is either we remove these two switch cases,
or we add these interface modes to the supported_interfaces array.

I'd rather those with mtk_eth_soc made the decision, even though it
is highly unlikely that these modes are used on the hardware they
have - as I don't have any mediatek hardware.

Thanks.
