To get a YCBCR420 output from intel platforms, we need one scaler to scale down YCBCR444 samples to YCBCR420 samples. This patch: - Does scaler allocation for HDMI ycbcr420 outputs. - Programs PIPE_MISC register for ycbcr420 output. V2: rebase V3: rebase V4: rebase V5: addressed review comments from Ander: - No need to check both scaler_user && hdmi_output. Check for scaler_user is enough. V6: rebase V7: Do not create a new scaler user, use existing pipe scaler user. V8: rebase V9: Addressed review comments from Ville: - Remove leftover comment for HDMI scaler user. - Remove unnecessary blank line. - Make scaler alocation failure a DEBUG log instead of ERROR.
