    mtd: mchp23k256: add partitioning support
    
    Setting the of_node for the mtd device allows the generic mtd code to
    setup the partitions.
    
    [Editorial note (Brian): patch still pending on fixing up the "aligned
    to eraseblock" partition sanity check, given that this SRAM has no
    eraseblocks.]
