    [MTD] mtdcore.c: share syms with mtd_blkdev.c
    
    Fix the sparse warnings generated by the implicit
    dependency of mtd_blkdevs.c and mtd_core.c for the
    two symbols mtd_table and mtd_table_mutex. This is
    done by adding an local header file mtdcore.h to
    define these (including the warning about the
    non-proliferation of these symbols).
