[RESEND PATCH v4 2/3] cmd: mtd: add nand_write_test command support

Some nand flashes (like spi-nand one) are registered with mtd subsystem only, thus nand command can't be used to work with such flashes. As result some functionality is missing. This patch implements 'nand torture' functionality for mtd command. Signed-off-by: Mikhail Kshevetskiy --- cmd/Kconfi
