[v2,0/4] drm/bridge: dw-hdmi: Various updates

Message

This series fixes multiple issues I found out.
Patch 1 fixes reporting colorimetry in AVI frame.
Patch 2 sets scan mode to underscan which is in line with most other
hdmi drivers.
Patch 3 aligns RGB quantization to CEA 861 standard.
Patch 4 reworks is_color_space_conversion(). Now it checks only if
color space conversion is required. Patch adds separate function for
checking if any kind of conversion is required.

Please take a look.

Best regards,
Jernej

Changes from v2:
- added tags
- replaced patch 2 with patch 4
- renamed rgb conversion matrix and make hex lowercase
- move logic for checking if rgb full to limited range conversion is
  needed to is_color_space_conversion()
- reworked logic for csc matrix selection
