ethernet: Extend device_get_mac_address() to use NVMEM

Browse source

[ Upstream commit d2d3f529e7 ]

A lot of modern SoC have the ability to store MAC addresses in their
NVMEM. So extend the generic function device_get_mac_address() to
obtain the MAC address from an nvmem cell named 'mac-address' in
case there is no firmware node which contains the MAC address directly.
