There was NVMEM support added directly to of_get_mac_address, and it uses
nvmem_get_mac_address under the hood, so we can remove it. As
of_get_mac_address can now return ERR_PTR encoded error values, adjust to
that as well.

 Changes since v2:

 * ERR_PTR and EPROBE_DEFER handling

 Changes since v3:

  * IS_ERR_OR_NULL -> IS_ERR
