platform/x86/intel/pmc: Move common code to core.c
Functions like mtl_set_device_d3() and mtl_punit_pmt_init() were added for
Meteor Lake. To be able to use them in Arrow Lake and future platforms,
move them to core.c.
Also, to support different guids, add guid argument in
pmc_core_punit_pmt_init() and to support different PCI function numbers,
add func arg in pmc_core_ssram_init().
