clocksource: h8300_timer8: Don't reset rate in ->set_state_oneshot()
With the upcoming NTP correction related rate adjustments to be implemented in the clockevents core, the latter needs to get informed about every rate change of a clockevent device made after its registration. Currently, h8300_timer8 violates this requirement in that it registers its clockevent device with the correct rate, but resets its ->mult and ->rate values in timer8_clock_event_start(), called from its ->set_state_oneshot() function. It seems like commit 4633f4cac85a ("clocksource/drivers/h8300: Cleanup startup and remove module code."), which introduced the rate initialization at registration, missed to remove the manual setting of ->mult and ->shift from timer8_clock_event_start(). Purge the setting of ->mult, ->shift, ->min_delta_ns and ->max_delta_ns from timer8_clock_event_start().
