Camelia Groza 8092e9d0e0 board: freescale: t208xrdb: fdt fixups under DM_ETH
Disable the FMan mEMAC 5 and 6 nodes from the fdt since they are not
available under the supported RCW. Also disable the associated
"fsl,dpa-ethernet" nodes that reference them.

This is a simplified version of the fdt_fixup_fman_ethernet call for
use under DM_ETH.
