[U-Boot] commit 26d6119 (fdt: Move fdt_fixup_ethernet to a common place) breaks vxWorks targets

Hello,

Moving the "fdt_fixup_ethernet(...)" call breaks vxWorks targets.

The MAC-address isn't updated in the device-tree anymore since the function never gets called on booting a vxWork kernel. I'll provide some patch to fix this.

cheers, Hannes
