If the hdmi color format is set to DRM_HDMI_OUTPUT_YCBCR_HQ or DRM_HDMI_OUTPUT_YCBCR_LQ when the system boot, The actual color formats is YUV444/YUV422/YUV420. This leads to misjudgment that the color format has changed, hdmi will be reset. That cause display err between kernel logo and bootanimation.
