This simplifies the RTC procfs 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 also removes the class_interface hook, now that its last remaining user is
gone. (That API is usable only with a "struct class_device".)
It's another step towards being able to remove "struct class_device".
