watchdog: constify watchdog_ops structures
Check for watchdog_ops structures that are only stored in the ops field of
a watchdog_device structure. This field is declared const, so watchdog_ops
structures that have this property can be declared as const also.
The semantic patch that makes this change is as follows:
