This patch is to support Freescale sata driver with dts initialized. Also resolved the following problems.

[Peng Ma] Hi Stefan,
fsl_sata.c used to Non DM sata driver for some powerpc socs. Currently We only have one board that supports dts initialization. I will remove this old driver When all of our powerpc socs support DM.
I see, thanks. I just wanted to know, if this new SATA driver is a meant as a replacement for the old non-DM driver.
[Peng Ma] Hi Stefan,
I am so sorry to reply late, Other Non dts powerpc board need the old sata driver, so the new Sata driver does not replace the so far.
Just curious: Which are the "other non dts powerpc boards"? Are there still many? Is there a plan to move them to DT as well? Or should they perhaps be dropped from mainline if not converted to DT? What's stopping the conversion here?
Thanks, Stefan
