From: Tang Yuantian <Yuantian.Tang at freescale.com>
Freescale ARM-based Layerscape LS102xA contain a SATA controller
which comply with the serial ATA 3.0 specification and the
AHCI 1.3 specification.
This patch adds SATA feature on ls1021aqds and ls1021atwr boards.
Signed-off-by: Tang Yuantian <Yuantian.Tang at freescale.com>

v2:
- rebase to latest git tree
- use micro SATA_ECC_REG_ADDR instead of hard coding
