Waddledee: Initial board file

This commit contains the initial code for waddledee, the ITE reference
board for dedede.  All of the GPIOs are defined, and any tasks that can
be enabled to begin with are.  Since the charger driver is still in
progress, this commit undefs any charger related baseboard features,
and they will be re-enabled once the driver is ready.
