Jia-Ju Bai 298c854520 rtc: r7301: Fix a possible sleep-in-atomic bug in rtc7301_set_time 
The driver may sleep under a spinlock.
The function call path is:
rtc7301_set_time (acquire the spinlock)
  usleep_range --> may sleep

To fix it, usleep_range is replaced with udelay.

This bug is found by my static analysis tool(DSAC) and checked by my code review.
