net: phy updates

[Sascha Hauer]

This series gets direct phy register accesses out of the generic code
path. This is necessary for phys which have a different register
layout not handled correctly by the generic code. Also the phy link
status check is moved to a poller callback. With this we get periodic
link status updates printed on the console.
