    mtd: plat_nand: remove redundant return value check of platform_get_resource()
    
    Remove unneeded error handling on the result of a call
    to platform_get_resource() when the value is passed to
    devm_ioremap_resource(). And move those two call together
    to make the connection between them more clear.
