[U-Boot] [PATCH] mtd: nand: Kconfig Setup missing NAND dependencies based on ARCH

[Adam Ford]

To avoid clutter in the NAND menu, let's make the NAND controllers
dependent on which ARCH type uses them.  This way, we cannot
accidentally try to enable a NAND controller that doesn't exist.

This is based on Convert CONFIG_SYS_MAX_NAND_DEVICE to Kconfig and
add CONFIG_NAND that was just submitted.
