board: stm32mp1: add support of nor1 device in dfu command

Add support of mtd backend for nor1 when this device is present on the
board, on STM32MP157C-EV1 for example, as the support of several MTD
spi-nor instance are now supported with commit b7f060565e31 ("mtd:
spi-nor: allow registering multiple MTDs when DM is enabled").
