Chris Packham	d6c0d7087f	drivers: rtc: max313xx: provide read8/write8 ... In some designs the MAX313xx RTC may need calibration to cope with oscillator inaccuracies. Provide read8/write8 ops so that the registers can be accessed. Because the driver covers a range of MAX313xx variants no attempt is made to ensure the register is valid.
