PATCH v3 1/1 arm: ls1021a: Add sata support on qds and twr board

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.

v3:
- refactor the framework
- replace hard coding with MICRO
v2:
- rebase to latest git tree
- use micro SATA_ECC_REG_ADDR instead of hard coding
