[Yuantian.Tang at freescale.com]

From: Tang Yuantian <Yuantian.Tang at freescale.com>

Added sata node to ls1021aqds and ls1021atwr board to support
sata function.

Signed-off-by: Tang Yuantian <Yuantian.Tang at freescale.com>
---
v4:
	- sorted the node alphabetically
v3:
	- refine the title and commit message
	- added a status property so that sata can be controlled
	by board specific dts.
v2:
	- put reg-names right after reg property
