[PATCH] ARM: stm32: Default dfu_alt_info for STM32MP13xx SPI NOR

[Marek Vasut]

Define dfu_alt_info with SPI NOR layout to make it easy to
install or update bootloader in the SPI NOR using dfu-util.

Use the following U-Boot commands to start DFU mode:
"
=> sf probe && dfu 0 mtd
"

Use the following dfu-util invocation on Host PC to install binaries:
"
$ dfu-util -w -a 0 -D build/stm32mp1/release/tf-a-stm32mp135f-dhcor-dhsbc.stm32
$ dfu-util -w -a 1 -D build/stm32mp1/release/tf-a-stm32mp135f-dhcor-dhsbc.stm32
$ dfu-util -w -a 2 -D build/stm32mp1/release/fip.bin
"
