boot: Move code to common/
Normally code in commands/ shall only do the option parsing whereas the functionality shall be in common/ to make the code usable from C aswell. Do this in the boot code aswell, move it to common/boot.c and add the function prototypes to include/boot.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
