soc/intel: Move pmc_soc_set_afterg3_en() to pmutil.c
Commit 2c26108208e4aa48de21be576ab6cad9286d7934 moved this function to
pmutil.c for Tiger Lake. Do this to all other platforms for consistency.
For Skylake, __SIMPLE_DEVICE__ preprocessor guards are no longer needed.
With this change, pmc.c is only needed in ramstage. Adjust Makefile.inc
accordingly, and drop ENV_RAMSTAGE guards from Skylake.
