This looks like a regression, we intentionally made them private and they
should be moved into a proper driver instead of being globally visible.

These should be in DT only.

The RST bits should probably go into a drivers/reset driver. Not sure what the
other registers do, but I'm sure we can find a driver for these too, possibly
they should be part of the PHY driver?

You leave the FIXME in place but move away the definitions it talks about.
Please fix the problem instead.
