This patch adds DTS definition of the imx278 based XEA board.

Signed-off-by: Lukasz Majewski <lukma@denx.de>

---
Changes for v3:
- Remove meaningless 'regulator-always-on' and 'enable-active-high'
- Provide proper order for ssp{023}
- Change memory start address to @40000000

Changes for v2:
- Fix 'memory' node and remove regulators subnode
- Rename 'flash0: s25fl256s0@0' to flash@0
- Add proper compatible for XEA board
