net: ethernet: bcmgenet: use phydev from struct net_device

Browse Source 
The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phy in the private structure, and update the driver to use the
one contained in struct net_device.
