[WATCHDOG] w83697hf/hg WDT driver - patch 2

This is patch 2 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:
 - wdt_io is 2 bytes long. We should do a
   request_region for 2 bytes instead of 1.
