    GPIO pins exposed on Seeeduino Xiao (and compatible devices) headers.

    The Seeeeduino Xiao layout provides two headers, along opposite
    edges of the board.

    Proceeding counter-clockwise:
    * A 7-pin Digital/Analog Input header.  This has input signals
      labeled from 0 at the top through 6 at the bottom.
    * An 7-pin header Power and Digital/Analog Input header.  This
      has three power pins, followed by four inputs labeled 10 at the
      top through 7 at the bottom.

    This binding provides a nexus mapping for 10 pins where parent pins 0
    through 10 correspond to D0 through D10, as depicted below:

        0 D0                     5V   -
        1 D1                     GND  -
        2 D2                     3V3  -
        3 D3                     D10 10
        4 A4                     D9   9
        5 D5                     D8   8
        6 D6                     D7   7
