watchdog: f71808e_wdt: indicate WDIOF_CARDRESET support in watchdog_info.options

commit e871e93fb08a619dfc015974a05768ed6880fd82 upstream.

The driver supports populating bootstatus with WDIOF_CARDRESET, but so
far userspace couldn't portably determine whether absence of this flag
meant no watchdog reset or no driver support. Or-in the bit to fix this.
