nuc900/rtc: change the waiting for device ready implement
- add an mdelay(1) to the polling loop to cause less frequent access to
the hardware register.
- change the return value from ENODEV to EPERM if the loop timed out. I
think the 'Operation not permitted' description is more suitable for the
meaning of 'check_rtc_access_enable()' function, it just be used to
judge rtc access operation is permitted or not.
