RTC for 4.9

Subsystem:
 - delete owner assignment in multiple drivers
 - constify rtc_class_ops structures

Drivers:
 - ac100: support clock-output-names
 - cmos: properly handle ACPI alarms and quirky BIOSes and other fixes
 - ds1307: fix century bit support while staying comaptible with previous
   behaviour by default
 - ds1347: switch to regmap
 - isl12057 is now handled by ds1307
 - omap: support external wakeup
 - rv8803: allow to disable voltage drop detection
rtc: rv8803: set VDETOFF and SWOFF via device tree

There might be designs where the power supply circuit is designed
in a way that VDETOFF and SWOFF is required to be set. Otherwise the
RTC detects a power loss. Add a device tree interface for this.
