mtd: nand: fix for drop unnecessary partition parser data

From Stephen:

    Hi Brian,

    After merging the l2-mtd tree, today's linux-next build (powerpc
    ppc44x_defconfig) failed like this:

    drivers/mtd/nand/ndfc.c: In function 'ndfc_chip_init':
    drivers/mtd/nand/ndfc.c:177:2: error: 'ppdata' undeclared (first use in this function)
      ppdata.of_node = flash_np;
      ^

    Caused by commit

      a61ae81a ("mtd: nand: drop unnecessary partition parser data")

The flash node is already correctly assigned using the new helper
(nand_set_flash_node()) so the correct fix is indeed to simply drop this
line.
