2.17.1
komeda display HWs have kinds of coefficient tables for various purposes
like gamma/degamma. ususally these tables are shared by multiple HW
component and have limited number.
Introduce komeda_coeffs_table/manager for describing and managing these
tables, like table reuse, racing.

2.17.1
Many komeda component support color management like layer and IPS, so
komeda_color_manager/state are introduced to manager gamma, csc and degamma
together for easily share it to multiple componpent.
And for komeda_color_manager which:
- convert drm 3d gamma lut to komeda specific gamma coeffs
- gamma table management and hide the HW difference for komeda-CORE

- D71 has 3 global layer gamma table which can be used for all layers as
gamma lookup table, no matter inverse or forward.
- Add komeda_color_manager/state to layer/layer_state for describe the
color caps for the specific layer which will be initialized in
d71_layer_init, and for D71 only layer with L_INFO_CM (color mgmt) bit
can support forward gamma, and CSC.
- Update komeda-CORE code to validate and convert the plane color state to
komeda_color_state.
- Enable plane color mgmt according to layer komeda_color_manager
