Provide a common CBFS wrapper for SPI storage
Coreboot has all necessary infrastructure to use the proper SPI flash interface in bootblock for CBFS. This patch creates a common CBFS wrapper which can be enabled on different platforms as required. COMMON_CBFS_SPI_WRAPPER, a new configuration option, enables the common CBFS interface and prevents default inclusion of all SPI chip drivers, only explicitly configured ones will be included when the new feature is enabled. Since the wrapper uses the same driver at all stages, enabling the new feature will also make it necessary to include the SPI chip drivers in bootblock and romstage images. init_default_cbfs_media() can now be common for different platforms, and as such is defined in the library. BUG=none TEST=manual . with this change and the rest of the patches coreboot on AP148 comes up all the way to attempting to boot the payload (reading earlier stages from the SPI flash along the way).
