soc/intel/xeon_sp: Early programming of ACPI bar

ACPI bar was not programmed previously for which is needed to enable SMI's and
to check SMI status registers. The architecture of Lewisburg PCH is very
similar to SunrisePoint PCH thus we can use code from soc/intel/skylake.

TEST=build for Tiogapass and check ACPI base. Log message will now show
pmbase=501 (bit 0 is enable) instead of 0. Check by reading and writing
to io port 0x500.
