This allows the watchdog timer to work on my tegra124.
tegra_wdt specifies: compatible = "nvidia,tegra30-timer";
But the dtsi was only setting tegra20-timer, fix this
by adding tegra30-timer explicitly. This allows
the watchdog to work on my Jetson TK1.

I've applied this with a slightly reworded commit message. I haven't
added a Cc: stable because I don't think this qualifies. There is no
regression that this fixes, or any bugs. It enables a feature, which
is useful, but doesn't need to go to stable in my opinion.
If you or anyone else feels strongly I can be convinced to add it,
though.
