drivers/spi: move cbfs_spi.c location

The common boot device spi implementation is very much
    specific to SPI flash. As such it should be moved into
    that subdirectory. It's still a high-level option but
    it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally
    that allows the auto-selection of SPI_FLASH by a platform
    selecting COMMON_CBFS_SPI_WRAPPER which allows for culling
    of SPI_FLASH selections everywhere.
