    beaglebone: Update bootblock.c to use new structs/code
    
    New structures and functions have been added to make it easier and
    clearer to talk to GPIOs, configure the clock module, and toggle the
    LEDs. Use that code in bootblock.c instead of doing those things
    manually with hardcoded addresses.
