Kevin O'Connor a6de2184ba stepper: Optimize for case where add is zero
At high rates, the "add" field is frequently zero.  It's possible to
optimize for that case.

Kevin O'Connor bb3b881e21 docs: Change the debugging docs to recommend a serial baud rate of 250000
A baud of 250000 is a better choice for production use.  It's better
to test with that rate also.

Kevin O'Connor 91e7807af6 avr: Add config option to clear the CPU prescaler
Some AVR chips ship with a 1/8th clock divisor set.  Add a compile
time option to manually clear this field at startup.

Kevin O'Connor 2a17d9457a avr: Eliminate gpio_adc_info struct in gpio adc pin definitions
The gpio_adc_info only contains a single uint8_t field - it's simpler
to use an array of uint8_t instead.
