rtc: pcf8523: properly handle oscillator stop bit
The time and date register of the pcf8223 are undefined after a power
reset. Properly handle the OS bit and return -EINVAL when that bit is set.
It is properly removed when setting the time.
This solves an issue where the time and date may be valid for
rtc_valid_tm() but is not the current time.
