drm/mediatek: mtk_disp_gamma: Fix breakage due to merge issue 



While the commit that was sent to the mailing lists was fine, something
happened during merge and the mtk_gamma_set() function got broken as
a writel() was turned into a readl().

Fix that by changing that back to the expected writel().
