Wolfram Sang a3e32b41c2 dt-bindings: watchdog: factor out RZ/N1 watchdog
Renesas created different watchdog IPs but they are all handled in the
same binding documentation. This leads to a lot of conditional handling
which makes it unnecessarily hard to add new items. Factor out the RZ/N1
watchdog to make handling easier.
