imx: Add support for i.MX28 based XEA board
This patch introduces support for i.MX28 based XEA board.
This board supports DM/DTS in U-Boot proper as well as DM aware drivers
in SPL (u-boot.sb) by using OF_PLATDATA.
More detailed information regarding usage of it can be found in
./board/liebherr/xea/README file.
