drm: bridge: dw-hdmi: fix VP_PR_CD pixel repetition factor configuration

Browse Source 
The configured value sets H13T PHY PLL to multiply pixel clock by the
factor in order to obtain the desired repetition clock. For the CEA
modes some are already defined with pixel repetition in the input video.
So for CEA modes this shall be always 0.
