pins: Support registering arbitrary chips that supply configurable pins

Browse source 
Allow multiple chips to provide pin mappings (not just the main mcu
chip).  Move the pin parsing from the mcu.py code to pins.py and
support mapping from pin descriptions to their corresponding chips and
parameters.
