[PATCH 25/41] clocksource: tegra20: Migrate to new 'set-state' interface

Migrate tegra20 driver to the new 'set-state' interface provided by
clockevents core, the earlier 'set-mode' interface is marked obsolete
now.

This also enables us to implement callbacks for new states of clockevent
devices, for example: ONESHOT_STOPPED.

Replace with 'tegra_timer_shutdown'
