This series enable CRTC color-mgmt for komeda driver, for current komeda HW
which only supports color conversion and forward gamma for CRTC.
This series actually are regrouped from:
- drm/komeda: Enable layer/plane color-mgmt:
https://patchwork.freedesktop.org/series/60893/
- drm/komeda: Enable CRTC color-mgmt
https://patchwork.freedesktop.org/series/61370/
For removing the dependence on:

Lowry Li (Arm Technology China) (1):
drm/komeda: Adds gamma and color-transform support for DOU-IPS
james qian wang (Arm Technology China) (3):
drm/komeda: Add a new helper drm_color_ctm_s31_32_to_qm_n()
drm/komeda: Add drm_lut_to_fgamma_coeffs()
drm/komeda: Add drm_ctm_to_coeffs()
v2:
Move the fixpoint conversion function s31_32_to_q2_12() to drm core
as a shared helper.
v4:
Address review comments from Mihai, Daniel and Ilia.

2.20.1
From: "Lowry Li (Arm Technology China)" <[email protected]>
Adds gamma and color-transform support for DOU-IPS.
Adds two caps members fgamma_coeffs and ctm_coeffs to komeda_improc_state.
If color management changed, set gamma and color-transform accordingly.
