soc/intel/xeon_sp/cpx: Modify PCH_IOAPIC_BUS_NUMBER
The PCH IOAPIC is not PCI discoverable.
Linux checks the BDF set in DMAR against the PCI class if it is a PIC,
which 00:1F.0 for instance isn't.
The SINIT ACM on the other hand bails out with ERROR CLASS:0xA, MAJOR
3, MINOR 7 if the BUS number is 0.
