[PATCH v1 4/5] drm/mediatek: mtk_dpi: Allow additional output formats on MT8195/88

[AngeloGioacchino Del Regno]

Allow additional output formats in both DPI and DP_INTF blocks of
the MT8195 and MT8188 SoCs (as the latter is fully compatible with,
hence reuses, the former's platform data for both blocks) by adding:

1. New formats to the `mt8195_output_fmts` array for dp_intf,
   lacking YUV422 12-bits support, and adding RGB888 2X12_LE/BE
   (8-bits), BGR888 (8-bits) RGB101010 1x30 (10-bits), and YUV
   formats, including YUV422 8/10 bits, and YUV444 8/10 bits; and
2. A new `mt8195_dpi_output_fmts` array for DPI only, with all of
   for formats added to dp_intf and with the addition of the
   YUYV12_1X24 (YUV422 12-bits) output format.
