RTC for 4.8

Browse source 
Cleanups:
  - huge cleanup of rtc-generic and char/genrtc this allowed to cleanup rtc-cmos,
   rtc-sh, rtc-m68k, rtc-powerpc and rtc-parisc
  - move mn10300 to rtc-cmos
 
 Subsystem:
  - fix wakealarms after hibernate
  - multiples fixes for rctest
  - simplify implementations of .read_alarm
 
 New drivers:
  - Maxim MAX6916
 
 Drivers:
  - ds1307: fix weekday
  - m41t80: add wakeup support
  - pcf85063: add support for PCF85063A variant
  - rv8803: extend i2c fix and other fixes
  - s35390a: fix alarm reading, this fixes instant reboot after shutdown for QNAP
    TS-41x
  - s3c: clock fixes
