[PATCH v2] arc_emac: drop redundant mac address check

[PATCH v2] arc_emac: drop redundant mac address check

[Luka Perkov]

Checking if MAC address is valid using is_valid_ether_addr() is already done in
of_get_mac_address(). While at it, reorganize checking so it matches checks in
other drivers.

Applied.
