Kevin O'Connor 8e1c0941b0 generic: Add new file generic/io.h and move read/writeb() to it 
Move the definitions of the readb() style functions to a new header
generic/io.h.  This eliminates the dependency of stdint.h on
compiler.h.

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 2a17d9457a avr: Eliminate gpio_adc_info struct in gpio adc pin definitions
