net: introduce phylib

Adapt phylib from linux

switch all the driver to it
reimplement mii bus

This will allow to have
 - phy drivers
 - to only connect the phy at then opening of the device
 - if the phy is not ready or not up fail on open

Same behaviour as in linux and will allow to share code and simplify porting.
