Add a new helper function drm_color_ctm_s31_32_to_qm_n() for driver to
convert S31.32 sign-magnitude to Qm.n 2's complement that supported by
hardware.
V4: Address Mihai, Daniel and Ilia's review comments.
V5: Includes the sign bit in the value of m (Qm.n).
V6: Allows m = 0 according to Mihail's comments.
V7: Address Mihail's comments.
V8: Use type 'u32' to replace 'uint32_t'
V9: Rebase.

This function is for converting drm_color_ctm matrix to komeda hardware
required required Q2.12 2's complement CSC matrix.
v2:
Move the fixpoint conversion function s31_32_to_q2_12() to drm core
as a shared helper.

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.
