video: dcu: enable pixel clock after initialization

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.
