soc/intel/apollolake: Fix overlapping ACPI resource ranges

The address space allotted to MCRS in the northbridge needs to be exclusive
of the address space allotted to the GPIO controllers in the southbridge,
otherwise Windows complains of overlapping resource ranges and disables
the GPIO controllers. To prevent overlap, use CONFIG_PCR_BASE_ADDRESS
to set the upper bound of MCRS rather than MMCONF.

Test: boot Windows 10/11 on google/{reef,ampton} and verify that
GPIO controllers are indicated as without fault in Device Manager.
