Different hardwares can have different no of coefficients for palette correction. Also the correction can be applied after/before color transformation (CTM) unit in the display pipeline. This patch adds two new read-only properties, - cm_coeff_before_ctm_property: A platform driver should use this property to show supported no_of_coefficients for palette correction, which gets applied before ctm correction. - cm_coeff_after_ctm_property: A platform driver should use this property to show supported no_of_coefficients for palette correction, which gets applied after ctm correction.
