rtc: remove /sys/class/rtc-dev/*
This simplifies the /dev support by removing a superfluous class_device (the
/sys/class/rtc-dev stuff) and the class_interface that hooks it into the rtc
core. Accordingly, if it's configured then /dev 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".
