If it is only about bindings then there is little benefit in keeping
this, just drop this case. However you cannot drop it from DTS, so this
is a bit pointless.
Lack of MST support is not informative enough to claim it is not
compatible with 8350. For example if it was working fine via fallback,
then that statement is simply not correct.
And it HAD to work fine, because there is nothing binding to
qcom,sm6350-dp.
