soc/intel/cmn/acpi: Add support for `PCR_BASE_ADDRESS` above 4 GiB

This change updates the Northbridge ASL to conditionally include a
QWordMemory resource for `SM01` when the `CONFIG_PCR_BASE_ADDRESS`
is above 4 GiB.

If `CONFIG_PCR_BASE_ADDRESS` is below 4 GiB, or falls within the
PCH reserved range, the existing handling of `SM01` remains unchanged
(as a DWordMemory resource).

TEST=Built with CONFIG_PCR_BASE_ADDRESS both above and below 4 GiB,
verified ASL output.
