Makefile.inc: Create function to add a file to CBFS 

This function can be called to more easily add a file to CBFS.

Additional file attributes can be added later:

cbfs-files-y += pagetables
pagetables-file := $(objcbfs)/pt
pagetables-type := raw
pagetables-compression := none
pagetables-COREBOOT-position := $(CONFIG_ARCH_X86_64_PGTBL_LOC)

becomes

$(call add-cbfs-file-simple, pagetables,  $(objcbfs)/pt, raw, none )
pagetables-COREBOOT-position := $(CONFIG_ARCH_X86_64_PGTBL_LOC)

This is especially useful inside macros where you may want to add
an unknown number of entries.
