Add support for the SPI serial flash host controller found on many Intel CPUs including Baytrail and Braswell. The SPI serial flash controller is used to access BIOS and other platform specific information. By default the driver exposes a single read-only MTD device but with a module parameter "writeable=1" the MTD device can be made read-write which makes it possible to upgrade BIOS directly from Linux.
