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.
