[PATCH v5 2/9] timer: Add helper for drivers using timebase fallback

[Rick Chen]

> This function is designed to be used when a timer used to be initialized by
> the cpu (e.g. RISC-V timers), but now is initialized by dm_timer_init. In
> such a case, the timer may prefer to use the clocks and clock-frequency
> properties, but should be able to fall back on using the cpu's
> timebase-frequency.
