Makefile.mk,cpu/intel/fit/Makefile.mk: introduce CBFS_REGIONS

Browse source 
Take advantage of cbfstool's ability to operate on multiple regions and
introduce a variable with a list of main CBFS regions: it's just
"COREBOOT" in most cases, but becomes "COREBOOT,COREBOOT_TS" when Top
Swap update mechanism is enabled (see [0]).

This is meant to simplify Makefiles by avoiding extra branches in
existing and future changes.
