Missing .reg_bus_bw, LGTM otherwise

Dmitry, I do not have the exact value yet.

Can I come back with a subsequent (different) patch to add it at a later stage
when I have that information?

I see no point in holding display support any further since it works
fine with the default bandwith.

If yes, I'll respin this series right away, but without the reg_bus_bw.

Please add a TODO or FIXME comment there.

I have not heard back from the clock team on the values.

But, what I can confirm at this point is for basic functional display 
support, we could let it go back to the default value which we have 
hard-coded and fill up this entry later.
