ARM: dts: imx6q-utilite-pro: enable 2nd display pipeline
Apart from the already enabled Designware HDMI port, the Utilite Pro has a second display pipeline which has the following shape: IPU1 DI0 --> Parallel display --> tfp410 rgb24 to DVI encoder --> HDMI connector. Enable support for it. In addition, since this pipeline is hardwired to IPU1, sever the link between IPU1 and the SoC-internal Designware HDMI encoder forcing the latter to be connected to IPU2 instead of IPU1. Otherwise, it is not possible to drive both displays at high resolution due to the bandwidth limitations of a single IPU.
