powerpc/t1040qds: Add Video - HDMI support
T1040 has internal display interface unit (DIU) for driving video.
T1040QDS 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 T1040QDS.
This patch add support to
-enable Video interface for T1040QDS
-route qixis multiplexing to enable DIU-HDMI interface on board
-program DIU pixel clock gerenartor for T1040
-program HDMI encoder via I2C on board
