drivers: handle I2C_TRANSFER return value consistently. Some I2C peripherals transfers return zero on success, others number of completed transfers. Make drivers robust against this.

RTC: add interface for check if RTC time has been set
...
New interface allows checking if RTC time has been set. This allows to application to detect if RTC has valid time (after
reset) or should application attempt to get real time by other means (for example, by launching ntpclient or GPS).
