layerscape: fix Ethernet/DPAA/FMAN on Traverse boards after DTS refresh 

Patch 303 is required for Traverse LS1043 targets when using the NXP DPAA1 driver.
The recent refresh of 4.9 patches on layerscape changed how FMan/BMan memory regions
were defined and meant Ethernet stopped working on these boards.

(Note that these definitions are only required for NXP's Ethernet driver, the new
upstream driver in >=4.15 works using the DTS provided in files/)
