mtd: nand: lpc32xx_mlc: drop custom write_page callback
This driver doesn't need its own custom chip->write_page callback; the only "custom" requirement is that this driver does not support subpage writes, which we can avoid using the NAND_NO_SUBPAGE_WRITE flag. With NAND_NO_SUBPAGE_WRITE, the default routine (nand_write_page()) should perform the equivalent operations.
