Well, except Roger's feedback, there were complete silence so far.
Note that simple fix was posted in February, this was rejected as
we should aim towards clean DT only driver. And here we are with
some doubts.

As I have no hardware nor any special knowledge going prior
initial driver commit it is rather hard to send "related dts changes"
given simple fact, that I'm unsure whenever we need to distinguish
between OMAP2 and OMAP3. Based on that we need either one or
two compatible strings.

Having two is safe, but u-boot will be unable to bring onenand equipped
igep up.
