Documentation: OMAPDSS: move sysfs documentation to ABI

Hi

In Documentation/arm/OMAP/DSS, there is a description of the DSS and FB sysfs
interfaces which could be moved to Documentation/ABI.

Would such a change be useful? I can see that the sysfs interface is still in
testing.

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.
