I am curious if anyone has feedback on this generic PHY driver? Patches
on MACB landed in net-next [0]. If the phy-eyeq5-eth driver approach
doesn't fly then I should sync with net land to revert MACB patches as
they are useless unless we have phy-eyeq5-eth merged.

V2 changelog at the moment (will wait a few more days before sending):
 - Acked-by: Conor Dooley on dt-bindings patch.
 - ptrdiff_t is printed using %td not %ld; warning on 32-bit archs [1].
