[PATCH V3 4/4] ARM: dts: omap5-uevm: Add uart pinctrl data

From: Sourav Poddar <sourav.poddar at ti.com>

Booting omap5 uevm results in the following error
"did not get pins for uart error: -19"

This happens because omap5 uevm dts file is not adapted to use uart through pinctrl
framework. Populating uart pinctrl data to get rid of the error.
