[WATCHDOG] w83697hf/hg WDT driver - patch 11 



This is patch 11 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:
 - Add w83697hf_select_wdt() and w83697hf_deselect_wdt()
   so that the start/stop/ping code can directly talk to
   the watchdog.
