atmel-samd: Introduce board reset mechanic used on CircuitPlayground

shared-bindings: Move enum-like classes out of DigitalInOut into digitalio.
...
Also, rename Direction.IN to Direction.INPUT and Direction.OUT to Direction.OUTPUT.
This simplifies using them. Prior to the nativeio split this would have led to
clutter in the top-level namespace but having digitalio prevents this.
Fixes #152

atmel-samd: Fix sharing TCCs by statically storing the current period.
...
A previous fix improved the duty_cycle channel value computation by
removing the reliance on the PER register which gave old values. It
saved the period on the object but failed to set anything for reused
timers. So, this breaks it out into a separate array that can be
shared across all object regardless of whether it used a new or
existing timer.

atmel-samd: Fix TCC1, its two channels and four wave outputs.

the incorrect channels.

atmel-samd: Set up the tcc_instance when using an already active TCC.
...
This fixes a hard lock that happens when using a second channel on an
in use TCC. The lock occurred when setting the duty cycle on the channel
because the hw address was not available to ASF.
Thanks to @ladyada for finding the bug.

atmel-samd: Handle TCC2 correctly. Unlike the other TCCs its 16bit
...
rather than 24bit. Setting the period for more than a 16bit number
caused the TCC to be in a weird state where resetting it would hard
crash.
