[PATCH] ARM: dts: imx6qdl-gw54xx: allow boot firmware to set eth1 MAC

[Tim Harvey]

The GW54xx has a PCIe based GbE as the 2nd ethernet device. The
boot firmware will populate the local-mac-address field of the
device aliased to ethernet1 thus adding the PCIe device to
dt allows boot firmware to set its MAC address.
