soc/intel/xeon_sp/skx: Configure IOAPICs

FSP only configures the PCH IOAPIC. Let coreboot reconfigure
all IOAPICs to assign unique IDs to each. 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.
