drivers/rtc/rtc-hym8563.c: return clock rate even when clock is disabled
When the clock is disabled, do not return a rate of 0 but instead return the rate the clock will be running at after it gets enabled. This prevents problems when the core clock code is trying to determine a suitable rate, while the clock is still off.
