[PATCH/RFC] configfs: Update docs to indicate sysfs & configfs usage is ok

[Andy Grover]

The docs state that sysfs and configfs are peers that meet different needs,
but doesn't explicitly make it clear that if a subsystem needs
functionality that spans both, it is preferable to use both instead of
trying to cram everything into one or the other.
