clocksource/drivers/timer-ti-dm: Add missing set_state_oneshot_stopped

To avoid spurious timer interrupts when KTIME_MAX is used, we need to
configure set_state_oneshot_stopped(). Although implementing this is
optional, it still affects things like power management for the extra
timer interrupt.

For more information, please see commit 8fff52fd50 ("clockevents:
Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state") and commit cf8c5009ee
("clockevents/drivers/arm_arch_timer: Implement
->set_state_oneshot_stopped()").

Fixes: 52762fbd1c ("clocksource/drivers/timer-ti-dm: Add clockevent and clocksource support")
