We've everything we need to support the gmac on Colombus, turn it on.

Signed-off-by: Hans de Goede <redacted>

I recall that the phy was powered by one of the AXP221 regulators,
does it require some additional stuff (like a recent u-boot), or does
it just work and my memory is bad :) ?

I think it just works, it MAY be connected to aldo1 but according to
the git history for the u-boot defconfig that one is used for wifi not
for the gmac, and we do not enable any other "spare" regulators in the
u-boot config.

I do not have any schematics, so no way to say for sure.

I can confirm that the GMAC work fine with the latest u-boot
master. Looking in the history we've always enabled ALDO1
on the Colombus in upstream u-boot, so this should all just work.

Could you test it with ALDO1 disabled in U-boot? That should give us
an answer.
