AngeloGioacchino Del Regno cfc146137a drm/mediatek: dp: Add missing error checks in mtk_dp_parse_capabilities ...

If reading the RX capabilities fails the training pattern will be set
wrongly: add error checking for drm_dp_read_dpcd_caps() and return if
anything went wrong with it.

While at it, also add a less critical error check when writing to
clear the ESI0 IRQ vector.
