soc/intel/xeon_sp: Share unlock_pam_regions()

unlock_pam_regions() is needed for SKX and CPX. Put the codes into
chip_gen1.c so that it could be shared among SoC generations.

After shared, unlock_pam_regions() is still called from SKX and
CPX SoC specific codes. SPR will also use chip_gen1.c, but it will
not call unlock_pam_regions().

TEST=Build and boot on intel/archercity CRB
