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

Freescale ARM-based Layerscape contains a SATA controller
which comply with the serial ATA 3.0 specification and the
AHCI 1.3 specification.
This patch adds SATA feature on ls2080aqds, ls2080ardb and
ls1043aqds boards.

Signed-off-by: Tang Yuantian <Yuantian.Tang@freescale.com>
---
v5:
- re-organize the code
v4:
- rebase to lastest git tree
- add another ARMv8 platform which is ls1043aqds
v3:
- rename ls2085a to ls2080a
- rebase to the latest git tree
- replace the magic number with micro variable
v2:
- rebase to the latest git tree
