drm/mediatek: mtk_dpi: Reorder output formats on MT8195/88

Browse source 
Reorder output format arrays in both MT8195 DPI and DP_INTF block
configuration by decreasing preference order instead of alphanumeric
one, as expected by the atomic_get_output_bus_fmts callback function
of drm_bridge controls, so the RGB ones are used first during the
bus format negotiation process.
