Subject: [PATCH mainline-linux 1/3] dt-bindings: watchdog: renesas,r9a09g057-wdt: Rework example

When the bindings for the Renesas RZ/V2H(P) SoC were factored
out IP WDT0 was selected for the example, however the HW user
manual states that only IP WDT1 can be used by Linux.

This commit is part of a series that removes WDT{0,2,3} support
from the kernel, therefore the example from the bindings has
lost its meaning.

Update the example accordingly.
