PATCH 1/1 ARM: Ux500: add synaptics RMI4 for Ux500 TVK DT

This adds the Synaptics RMI4 touchscreen to the Ux500 TVK user interface board. Tested on the U8500 HREFv60plus with the TVK UIB.

---
ARM SoC maintainers: please apply this patch directly for-next on some DT branch, I have no other Ux500 DT patches. These bindings are ACKed by Rob Herring in another thread so I think it's pointless to keep it out of tree.

Applied with slightly modified subject line.
