Add a driver for the Motorcomm yt8511 phy that will be used in the
production Pine64 rk3566-quartz64 development board.
It supports gigabit transfer speeds, rgmii, and 125mhz clk output.

Why is this "__maybe_unused"? This *.c file doesn't have any compilation option
to compile part of it.

The "__maybe_unused" is not needed in this case.

I was simply following convention, for example the realtek.c,
micrel.c, and smsc.c drivers all have this as well.

Maybe they have a reason, but this specific driver doesn't have such.
