RPI1B incorrectly identified as 3

[permezel]

I am trying to use the blinka on an RPI1B.
It identifies it as a 3. Accordingly, the i2c bus is identified as 1, not 0.

platform: 1
version: 3
board_id: raspi_3
Hello blinka!
Digital IO ok!

yeah the RPI1B isn't supported at this time, and the pinmap is all wrong because of that. if you're feeling up for adding a pin definition file for the pi 1, that would be awesome, and we'd make sure its detected right!

hiya try the 1.1.0 version of this library and Adafruit-PlatformDetect v0.0.8, it should now work with raspi 1's!
