ahci: Enable SB600 64bit DMA on Asus M3A
commit 3c4aa91f21f65b7b40bdfb015eacbcb8453ccae2 upstream. Like e65cc194f7628ecaa02462f22f42fb09b50dcd49 this patch enables 64bit DMA for the AHCI SATA controller of a board that has the SB600 southbridge. In this case though we're enabling 64bit DMA for the Asus M3A motherboard. It is a new enough board that all of the BIOS releases since the initial release (0301 from 2007-10-22) work correctly with 64bit DMA enabled.
