From: Yuantian Tang <andy.t...@nxp.com>
Make the code structure more general so that more socs can be
added easily and also remove speed limitation restriction.
Add the ls1012a sata support as well.

v3:
- remove #include <asm/arch/hardware.h> to fix compling warning
v2:
- refine the commit message
- use live tree functions
