rtc: ds1347: properly handle oscillator failures
The comment in the probe function stating that it disables oscillator stop detection and glitch filtering is incorrect as it sets bits 3 and 4 while it should be setting 5 and 6 to achieve that. Then, it is safe to assume that the oscillator failure detection is actually enabled. Properly handle oscillator failures by returning -EINVAL when the time and date are know to be incorrect and reset the flag when the time is set.
