drm/i915: prepare scaler for YCBCR420 modeset
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.
