soc/intel/apollolake: Add support for memory-mapped boot media
On Apollo Lake SPI flash is memory mapped. The mapping is different
to previous platforms. Only "BIOS" region is mapped in contrast to
whole flash. Also, the 128 KiB right below 4 GiB are being decoded by
readonly SRAM. Fail accesses to those regions, rather than returning
false data.
