PATCH 1/2 ARM: dts: imx6qdl-sabresd: Add touchscreen support

From: Fabio Estevam <[email protected]>

Hi Shawn,

I don't have access to a sabresd board at the moment, so could not test this.

Ok, I got a sabresd now and I realized that max11801 driver is also needed, so will work on it when time permits.
