  The r9a09g011 (a.k.a. RZ/V2M) comes with two watchdog IPs,
but Linux is only allowed one.

Add a node for the watchdog allowed to Linux to the SoC
specific dtsi.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
