This adds ACPI support for the APM X-Gene SATA ports. When the system
boots using ACPI table, the SATA ports are able to configure using the
values supplied by the ACPI table rather than the DTS.

When I was going through the PNP and ACPI ID list in
http://www.uefi.org/PNP_ACPI_Registry, I found that
there is no "APMC" for ACPI ID, I only found that there is
a PNP ID "APM" for Applied Memory Tech company, are
you using PNP ID for this one?
if not, I think you can send a request to UEFI and
request a new ACPI ID of "APMC" for Applied Micro, and then
submit the patch again.
How to send a request to register the ACPI ID, you can
refer to:

Hanjun, the documents are bit out of sync. We have received approval and
it is present in the document link below. I can also forward the approval letter
if it needed.

Sorry for missing this link, I think I should report this
inconsistency to ACPI spec working group and then update it
accordingly.
Thanks
Hanjun
