    mtd: nand: omap2: Fix module autoload
    
    If the driver is built as a module, autoload won't work because the module
    alias information is not filled. So user-space can't match the registered
    device with the corresponding module.
    
    Export the module alias information using the MODULE_DEVICE_TABLE() macro.
    
    Before this patch:
    
    $ modinfo drivers/mtd/nand/omap2_nand.ko | grep alias
    alias:          platform:omap2-nand
    
    After this patch:
    
    $ modinfo drivers/mtd/nand/omap2_nand.ko | grep alias
    alias:          platform:omap2-nand
    alias:          of:N*T*Cti,omap2-nandC*
    alias:          of:N*T*Cti,omap2-nand
