Move baytrail & fsp_baytrail to the common IFD interface.

- Add the common/firmware subdir to the baytrail & fsp_baytrail
    makefiles and remove the code it replaces.
    - Update baytrail & fsp_baytrail Kconfigs to use the common code.
    - Update the IFD Kconfig help and prompts for the TXE vs ME.
    - Whittle away at the CBFS_SIZE defaults.  All the fsp_baytrail
    platforms have their own defaults.
