[PATCH v3 3/4] mtd: rawnand: denali_dt: use UCLASS_MTD instead of UCLASS_MISC

[Masahiro Yamada]

UCLASS_MTD is a better fit for NAND drivers.

Make NAND_DENALI_DT depend on DM_MTD, which is needed to compile
drivers/mtd/mtd-uclass.c

Also, make ARCH_UNIPHIER select DM_MTD because all the defconfig
of this platform enables NAND_DENALI_DT.
