soc/intel/xeon_sp/skx: Configure IOAPICs

FSP only configures the PCH IOAPIC. Let coreboot reconfigure
all IOAPICs to assign unique IDs to each. Every IOAPIC has 8 GSIs,
and the IOAPICs on Socket1 start at GSI 72, thus calculate the excat
GSI address for each IOAPIC instead of assume it's a linear address space.

Unselect XEON_SP_HAVE_IIO_IOAPIC to prevent soc_get_ioapic_info()
from advertising wrong GSI addresses.

TEST: Booted on ocp/tiogapass with correct GSI bases asigned
      matching the _PRT advertised GSI bases.
