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.

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.

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.
