Watchdog: fix clearing of the watchdog interrupt
The bits in BRIDGE_CAUSE are documented as RW0C - read, write 0 to clear. If we read the register, mask off the watchdog bit, and write it back, we're actually clearing every interrupt which wasn't pending at the time we read the register - and that is racy. Fix this to only write ~WATCHDOG_BIT to the register, which means we write as zero only the watchdog bit.
