rtc: sysfs: move sysfs interface to Documentation/ABI

[Aishwarya Pant]

Hi

In Documentation/rtc.txt, there is a description of the sysfs
interface which could be moved to Documentation/ABI.

Would such a change be useful?

The ABI documentation format looks like the following:

What:          (the full sysfs path of the attribute)
Date:          (date of creation)
KernelVersion: (kernel version it first showed up in)
Contact:       (primary contact)
Description:   (long description on usage)

I am doing this in an exercise to move sysfs ABI interfaces (which are
documented) to their right place i.e. in Documentation/ABI along with the rest.
