sb/intel/i82801gx: Fix sata AHCI for desktop NM10/ICH7
Tested on Intel D510MO
Before this patch, I was unable to get the SATA controller into AHCI
mode. That is, I could never see PCI ID 8086:27c1 appearing on the bus.
With sata_ahci set, controller now goes into AHCI mode and works. 8086:27c1
Tested on X60 with AHCI enabled 8086:27c5 (AHCI mode for mobile ich7)
No regressions detected.
