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.
