soc/intel/apollolake: add support for IFWI region
On apollolake, the boot media layout is different in that the traditional
"BIOS" region contains another data structure with the boot assets such
as CSE firmware, PMC microcode, CPU microcode, and boot firmware to name
a few. This region is referred to as the IFWI. Add support for writing
the IFWI to a specified FMAP region to accommodate such platforms.
