rtc: isl12022: drop redundant write to HR register

There's nothing in the data sheet that says writing to one of the time
keeping registers is necessary to start the RTC. It does so at the
stop condition of the i2c transfer setting the WRTC bit:

  Upon initialization or power-up, the WRTC must be set to "1" to
  enable the RTC. Upon the completion of a valid write (STOP), the RTC
  starts counting.

Moreover, even if such a write to one of the timekeeping registers was
necessary, that's exactly what we do anyway just below when we
actually write the given struct rtc_time to the device.
