CRIS v10: Update driver for pcf8563

Browse source

- Use mutex instead of spinlock, fixes kernel bugzilla report 8339.
- Make sure that pcf8563_init can be called multiple times but only setup once.
- Change RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR
- Cache the voltage low value at driver init so the battery status
  information does not get 'accidentally' cleared when setting the RTC time.
- Add weekday handling.
- Correct leapyear handling to include 100 and 400 year exceptions.
- Correct whitespace and formatting errors.
- Remove useless CVS id tag.
