This is patch 15 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 2: 
   * the line reading "set second mode & disable keyboard ..."
     is plain wrong, the register being manipulated (CRF4) is
     the counter itself, not the control byte (CRF3) -- looks
     like it has been copied from another driver.
   * I think garbage is being written in CRF3 (the control word)
     as the timeout value is being stored in this register (such
     as 60 for 60 seconds).
   * We only want to set pin 119 to WDTO# mode and leave the rest
     of CR29 like it is.
   * Set count mode to seconds and not minutes.
