soc/intel/tigerlake: Move pmc_soc_set_afterg3_en to pmutil
pmc.c was included in the SMM object, but only needed the one function,
pmc_soc_set_afterg3_en. pmutil.c was already doing power management-
related functionality, and was included in SMM, so moving
pmc_soc_set_afterg3_en to pmutil.c allows pmc.c to be removed from the
SMM build.
