ARC: HSDK: Add tool and make target to generate bsp
HSDK board has preloader that reads SPI flash pages and searches
for a special image header to fetch and load binary.
Add tool, make target (bsp-generate) to generate
update script and u-boot binary image with header for preloader.
Also add script to default environment to apply updates.
