When people put a series of undocumented PHY register writes using
constants, we tell them it's firmware.

If these PHY registers are actually documented in the driver, write a
function in that driver which does the programming sequence, then add
a property that the driver looks for in order to determine whether to
call that sequence or not.

I don't want people putting random PHY raw programming sequences and
other crap like that into the OF device nodes.  It's extremely
inelegant and inviting abuse.
