From: Nishanth Menon <nm@xxxxxx>
OMAP5 and OMAP4 have different device instance offsets.
So to handle them properly, use a runtime detected instance offset
Other bit offsets and register offsets remained constant.
Creating a new function is not really worthwhile here as the logic
will be replicated without much benefit.
