SAS controller is always existed, so accessing SAS register don't
depend on PciBusDxe (pci enumeration).
Move the SAS module early in D06.fdf for dispatching SAS driver
early. This can avoid wait in BDS normally and reduce boot time.

This patch is relative with SasDriverDxe in edk2-non-osi.

I think you are saying that this change is only valid after the
update to SasDriverDxe in edk2-non-osi has been applied?
Or does it mean that it only improves performance after that
edk2-non-osi patch has been applied?

Please be more explicit in the commit message.

Other than that. I'm OK with this patch.
