56dd2d6ff1 soc/intel/apl: Warn if CBFS is outside the memory mapped area
As part of the memory mapped BIOS region is covered by SRAM, check
that CBFS always fits the effectively mapped region of flash. This
is usually taken care of by reserving the SRAM range in the FMAP
(e.g. as BIOS_UNUSABLE), but can be missed.

e70142c9c2 soc/intel/apollolake: Clean up code by using common FAST_SPI module
This patch currently contains the following -
 1. Use SOC_INTEL_COMMON_BLOCK_FAST_SPI kconfig for common FAST_SPI code.
 2. Perform FAST_SPI programming by calling APIs from common FAST_SPI library.
 3. Use common FAST_SPI header file.

31be2c969e soc/intel/common: remove mrc cache assumptions
Update the mrc cache implementation to use region_file. Instead
of relying on memory-mapped access and pointer arithmetic
use the region_devices and region_file to obtain the latest
data associated with the region. This removes the need for the
nvm wrapper as the region_devices can be used directly. Thus,
the library is more generic and can be extended to work on
different boot mediums.

5672dcd58c 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.
