Also, new debugfs entry is created to enforce YCbCr420 output format. This is required because of our driver policy. If a mode is supported in both RGB and YCbCr420 output formats by the sink, our policy is to try RGB first and fall back to YCbCr420, if mode cannot be shown using RGB. So, to test YCbCr420, we need a debugfs entry (force_dsc_ycbcr420) to force thisoutput format; so that YCbCr420 code gets executed.
