However, because of the bus format selection procedure in dw-hdmi, for HDMI2 sinks YUV420 is the format that will always be picked during the drm bridge chain check stage. Later on dw_hdmi_setup will configure a colour space based on the bus format that doesn't match the pixel value we had calculated as described above. Fix it by bringing back dw-hdmi bus format check when picking the right pixel clock.
