remove hardcoded gpio pins in modules/deepsleep.py

[basvs]

Possible better solutions:

• main.c
  move the methods to components/badge/

• modules/deepsleep.py
  expose the needed pins via badge.input_pins

I think we should always do the pin25 for touch wakeup thing probably in the mpr121 init . .

The bit in main.py is only for BPP afaik . . And they could/should be moved.

I couldn't find any reason not to use the input framework in main.c. I've created PR #125 for that.

The modules/deepsleep.py still contains pin 25. Not very important, but it would be nice if it uses a badge.deep_sleep() or if the deepsleep.py requests which pins are used for the input.

Ok, found an issue with it. The V3-Lite badge doesn't have a mpr121 chip. Pin 25 is always low and immediately triggers a wake-up on deep-sleep.
