powerpc/t1042RDB: Add Video - HDMI support
T1042 has internal display interface unit (DIU) for driving video. T1042RDB supports video mode via -LCD using TI enconder -HDMI type interface via HDMI encoder Chrontel, CH7301C encoder which is I2C programmable is used as HDMI connector on T1042RDB. This patch add support to -enable Video interface for T1042RDB -route qixis multiplexing to enable DIU-HDMI interface on board -program DIU pixel clock gerenartor for T1042 -program HDMI encoder via I2C on board This patch refer to the upstream diu patch (337b0c52b3296f371d04aef71a833e09110e0e6b) for T1040qds.
