    beaglebone: Update bootblock.c to take advantage of the 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.
