For MT8173, the gamma module is inside disp_aal. When we need to adjust gamma value, we need to use "has_gamma" to control gamma function inside disp_aal to adjust the gamma value. For successors like MT8183, disp_gamma is separated from disp_aal. We just need to control disp_gamma directly and don't need to control gamma function inside disp_aal. With this modification, the driver doesn't require any functional changes. We only update the dt-binding and DTS node to make it clear.
