====================
net: add a helpers for loading netdev->dev_addr from platform

Similarly to recently added device_get_ethdev_address()
and of_get_ethdev_address() create a helper for drivers
loading mac addr from platform data.

nvmem_get_mac_address() does not have driver callers
so instead of adding a helper there unexport it.
