drm/mediatek: add *driver_data for different hardware settings
There are some hardware settings changed, between MT8173 & MT2701: DISP_OVL address offset changed, color format definition changed. DISP_RDMA fifo size changed. DISP_COLOR offset changed. MIPI_TX pll setting changed. And add prefix for mtk_ddp_main & mtk_ddp_ext & mutex_mod. Signed-off-by: YT Shen <yt.shen@mediatek.com> Acked-by: CK Hu <ck.hu@mediatek.com>
