[ARM] pxa: Refactor Colibri board support code

- Move common function for all Colibri PXA3xx boards to the newly
  added colibri-pxa3xx.c
- Drop some unnecessary defines from colibri.h
- Make Kconfig reflect the fact that code for colibri 300 module does
  also work for the 310 model
- Give up on the huge pin config table which was messed up with lots of
  #ifdefs and switch over to locally defined tables for configured
  functions
