[media] V4L: Extend V4L2_CID_COLORFX with more image effects
This patch adds definition of additional color effects: - V4L2_COLORFX_AQUA, - V4L2_COLORFX_ART_FREEZE, - V4L2_COLORFX_SILHOUETTE, - V4L2_COLORFX_SOLARIZATION, - V4L2_COLORFX_ANTIQUE, - V4L2_COLORFX_SET_CBCR. The new V4L2_COLORFX_CBCR control is added to allow setting the fixed Cb, Cr values that replace chroma Cb/Cr coefficients in case of V4L2_COLORFX_SET_CBCR effect.
