[WATCHDOG] w83697hf/hg WDT driver - patch 14

This is patch 14 in the series of patches that converts
Marcus Junker's w83697hf watchdog driver to Samuel Tardieau's
w83697hf/hg watchdog driver.

This patch contains following changes:
 - Clean-up initialization code (part 1: remove
   w83697hf_select_wd_register() and
   w83697hf_unselect_wd_register() functions).
 - Make sure that the watchdog device is stopped
   as soon as we found it.
