Subject: net: fec: set mac address unconditionally

From: Gavin Schenk <[email protected]>

[ Upstream commit b82d44d78480faff7456e9e0999acb9d38666057 ]

If the mac address origin is not dt, you can only safely assign a mac address after "link up" of the device. If the link is off the clocks are disabled and because of issues assigning registers when clocks are off the new mac address cannot be written in .ndo_set_mac_address() on some soc's. This fix sets the mac address unconditionally in fec_restart(...) and ensures consistency between fec registers and the network layer.
