- Reorder node in devicetree (ordering by address)
- Remove unecessary lines in commits

Version 2:
- Add commit messages

Version 1:
- Initial commit

The purpose of this set of patches is to add a new watchdog driver for
stm32f429.
This driver was developed and tested on evaluation board stm32429i.
