34a8e501fe CRIS v10: Update driver for pcf8563
- 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.

e5d5cf2442 CRIS v10: Fix bugs in i2c_init and i2c_readreg
- Set the variable first to zero after first setup, so we can
  stop multiple calls to i2c_init from trying to setup i2c.

- The last byte read by the master in an i2c transfer needs to
  be NACKed, not ACKed.

- Also, remove useless CVS log and CVS id tags.
