When enabling the DCU and pixel clock, the test mode is activated
since this is the reset configuration. The test mode immediately
shows a red screen on a LCD. A moment later, the DCU gets
initialized properly.
This patch enables the pixel clock after initialization of the DCU
control register. This avoids this initial flicker on LCD screens.
While at it change the polarity of pixel clock to display samples
data on the rising edge.
