The driver must loads the no. of coefficients for color correction as per the platform capability during the init time. 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.
