apalis/colibri_t20/30: clean-up

Various clean-ups either in comments, order or spacing without any
functional impact:
- Add some comments in the device trees resp. reorder some parameters
  for consistency across all our modules.
- Sort some include files alphabetically (while leaving common.h on
  top of course).
- Streamline some comments in the configuration files and fix the
  spacing from using spaces to tabs.
