[PATCH 08/11] drm/mediatek: mtk_dp: Move max link rate to SoC specific data

[AngeloGioacchino Del Regno]

In preparation for adding support for the eDP IP found in the
MT8196 SoC, having a higher supported maximum link rate, move
this parameter to SoC data instead of statically assigning it
to the training info during initialization.
