machine/samd21: switch UART to use new pin configuration
...
This allows all possible UART pin configurations to be used and avoids
some tricky configuration.

machine/samd21: use pins specified in I2CConfig
...
Instead of configuring machine.I2C0, machine.I2C1, etc. statically,
allow the pins to be set using machine.I2CConfig. This will also
automatically configure the correct pin mode for each pin instead of
having to specify that manually.

machine/atsamd21: refactor SPI pin handling to only look at pin numbers
...
Pin mode and pad numbers are automatically calculated from the pin
numbers, returning an error if no pinout could be found.
