Jan Östlund 421a5ba24b rtc: bq32k: Fix handling of oscillator failure flag ...

While the oscillator failure flag is set, the RTC registers
should be considered invalid. bq32k_rtc_read_time() now
returns an error instead of an invalid time.

The failure flag is cleared the next time the clock is set.
