[PATCH v3 21/33] drm/mediatek: mtk_hdmi: Remove unused members of struct mtk_hdmi

[AngeloGioacchino Del Regno]

The hdmi_colorspace csp member of struct mtk_hdmi is initialized
once but then it's never used at all.
Remove said member and the only assignment to it as a cleanup.

Also remove the ibias, ibias_up, min_clock, max_clock, min_hdisplay
and max_vdisplay members, as those were really completely unused.

This commit brings no functional changes.
