This series is a simple improvement for timer-clint and timer-riscv:
Add set_state_shutdown for timer-clint, this hook is used when switching clockevent from timer-clint to another timer.
Add set_state_oneshot_stopped for both timer-clint and timer-riscv, this hook is to avoid spurious timer interrupts when KTIME_MAX is usd. Check commit 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state") for more information.
Since v1: - use U64_MAX instead of ULONG_MAX in clint_clock_shutdown, this is to "produce a 64-bit value on riscv32" as pointed out by Samuel
