[PATCH v1 2/6] ARM: boards: protonic-imx6: Don't fixup MAC address for disabled device

[Oleksij Rempel]

From: Robin van der Gracht <robin at protonic.nl>

The prtvt7 board variant has no enabled ethernet interface. For these
boards the MAC address in the RFID flash is unset or invalid and should
not be copied to the device-tree.
