Instead of defining them separately for each board, define them once in
the chip definition and later simply use &sercomUART1 etc. to refer to
them. This is simpler and less error-prone.
I found two bugs while working on this:
- The P1AM-100 board mixed SERCOM 5 and SERCOM 3. It looks like SERCOM
5 was intended, based on the used pins.
- The Adafruit Matrix Portal appears to have configured the wrong
interrupt.
Unfortunately, I can't test these fixes. However, they make it clear
that such a change is important to avoid bugs.
I tested this commit on the PyBadge and the Circuit Playground Express.
