Merge branch 'phy-internal' 



Florian Fainelli says:

====================
net: phy: Support "internal" PHY interface

This makes the "internal" phy-mode property generally available and
documented and this allows us to remove some custom parsing code
we had for bcmgenet and bcm_sf2 which both used that specific value.
====================
