DRM color manager allows the driver to showcase its best color correction capabilities using the cm_crtc_palette_capabilities_property.
This patch adds no of coefficitents for degamma color correction modes possible in CHV, in device info structure, which is: CGM Degamma(10 bit, CGM HW unit):- 65 coeff
These values will be loaded in cm_crtc_palette_capabilities_property during the CRTC init section, by color manager's attach function.
