soc/intel/alderlake: Fix PRMRR resource range calculation issue

This patch fixes an issue introduced with commit ca741055e
(soc/intel/adl: Add missing claimed memory regions) where PRMRR base
should be read using MSR 0x2a0 and mask from MSR 0x1f5 instead
System Agent PCI configuration space.

With this change, coreboot is able to read PRMRR base when the
PRMRR size > 0.

TEST=Able to read PRMRR base MSR 0x2a0 in proper with this CL.
