soc/intel/xeon_sp: Fix SKX SATA drive boot issue
SKX FSP doesn't support X2APIC setup, but CPX does. The CPX DMAR
table needs the X2APIC opt out flag set. This fixes the hang loading
a kexec'd kernel. The change is easy to see in the coreboot output:
[DMA Remapping table] Flags: 0x3
or in the DMAR ACPI table.
