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).
