soc/intel/tigerlake: Fix wrong operation region for CPU to PCH method
CPU to PCH method refers to PCH ACPI operation region which was wrongly
defined as SystemIO. This causes ACPI AE_LIMIT error from PM _DSW
method. Change the operation region from SystemIO to SystemMemory to
resolve this execution failure.
BUG=b:140290596
TEST=Built and booted to kernel. _DSW method executes successfully without
ACPI AE_LIMIT error.
