The port pins on the edge connector are different for v1 and v2

[tsadowski]

Hi,
I have been working on a Servo example. After it worked on a v1 board I tried it on a v2 board a well. I could compile and flash and it did run but the servos were not working. After some fiddling around I found out I needed to change the pins.

I don't know, what the best solution is. My preferred way would be to change the names of the unused pins in board.rs to the edge connector pin names. But this would be a breaking change.

What do you think?

Best Regards,
Torsten
