description:
Print the port name when gpio(4) attaches, makes it much easier to find
what port is connected to what gpio instance:
gpio0 at awingpio0: 18 pins
gpio0: port B
gpio1 at awingpio0: 25 pins
gpio1: port C
gpio2 at awingpio0: 28 pins
gpio2: port D
gpio3 at awingpio0: 12 pins
gpio3: port E
gpio4 at awingpio0: 12 pins
gpio4: port G
gpio5 at awingpio0: 28 pins
gpio5: port H
gpio6 at awingpio0: 22 pins
gpio6: port I
