ARM: stm32: Add update_sf script to install U-Boot into SF on DHSOM
Add script to read U-Boot from SD card and write it to matching
locations in the SPI NOR, thus making the SPI NOR bootable. The
script erases the entire SPI NOR, including U-Boot environment,
to make sure the installation is clean. To retain environment
from current running U-Boot, run 'saveenv' after running the
'update_sf' script.
