[WATCHDOG] fixed book E watchdog period register mask.
Luuk Paulussen [Thu, 15 Apr 2010 03:59:10 +0000 (15:59 +1200)]
A previous fix changed the WDTP function to use the period directly,
rather than subtracting from 63.  However the mask generation was
not changed, so the mask was coming out as 0.  This patch fixes it.
