This adds the GPIO names for the Raspberry Pi Zero. The GPIO lines
of the RPi Zero are almost identical to the Model A+ except:
* GPIO 35, 38, 40 and 45 are not connected
* Status LED is active low

The Raspberry Pi Zero is a minified version of model A+. It's
notable there is no PWR LED and the ACT LED is inverted.
Additionally the Pi Zero is capable of the USB peripheral mode.
