Subject: [PATCH v1] clocksource: tegra: Add nvidia,tegra30-timer compat

There are some differences between tegra20's timer registers and tegra30's
(and later).  For one thing, the watchdogs don't seem to be present in
tegra20.  Add this compatibility string in order to be able to distinguish
whether the watchdogs are there or not.
