rtc: simplified rtc sysfs attribute handling
This simplifies the RTC sysfs support by removing the class_interface that
hooks it into the rtc core. If it's configured, then sysfs support is now
part of the RTC core, and is never a separate module.
It's another step towards being able to remove "struct class_device".
