soc/intel: Always advertise MMIO window above 4G in ACPI tables
There should be no harm in advertising the MMIO window above 4G in
ACPI tables unconditionally. OS can decide whether or not to use the
window. This change removes the config option enable_above_4GB_mmio
and instead adds the correct MMIO window (above 4G) details to ACPI
tables always.
