Subject: [PATCH v2 1/2] net: ethernet: ethoc: use phydev from struct net_device

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.

Signed-off-by: Philippe Reynes <tremyfr@...il.com>

Changelog:
v2:
- remove the definition of phy in the ethoc private struct (thanks Tobias Klauser)
