Please split this into two:
1) Fix for it being optional
2) Removing support for phy-reset-active-high
The breakage is in net-next, so we are not in a rush, and we don't
need a minimum of patches. So since this is two logical changes, it
should be two patches.
Please also update the binding document to indicate that
'phy-reset-active-high' is no longer deprecated, it has actually been
removed. So we want the DT checking tools to error out if such a
property is found.
Thanks
Andrew
