[PATCH v2 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_SOCFPGA and ARCH_UNIPHIER select DM_MTD because
they use this driver.
