soc/intel/xeon_sp: Read IOAPIC ID from hardware

Currently coreboot hardcodes the same IOAPIC IDs as used on UEFI native,
however FSP does not program the IOAPIC IDs, except for PCH IOAPIC.

Drop existing code that hardcodes PCI addresses and IOAPIC IDs and
detect the IOAPIC inside the domain automatically, read the IOAPIC
base address and let existing code figure out the IOAPIC ID by reading
it back from HW.
