[PATCH v2 1/3] clocksource/drivers/timer-riscv: Add set_state_oneshot_stopped

[Jisheng Zhang]

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.

Check commit 8fff52fd5093 ("clockevents: Introduce
CLOCK_EVT_STATE_ONESHOT_STOPPED state") for more information.
