arm64: dts: qcom: x1e80100: Fix PHY for DP2

[ Upstream commit ba728bda663b0e812cb20450d18af5d0edd803a2 ]

The actual PHY used by MDSS DP2 is the USB SS2 QMP one. So switch to it
instead. This is needed to get external DP support on boards like CRD
where the 3rd Type-C USB port (right-hand side) is connected to DP2.
