[PATCH] arm64: dts: qcom: mahua-crd: Enable DisplayPort

[Nabige Aala]

Mahua CRD uses the same DisplayPort configuration as Glymur CRD.
Enable the two DisplayPort controllers associated with the
Type-C ports and define the supported link frequencies for
their outputs.

This patch enables the DisplayPort support in Mahua CRD.

Functional operation depends on following PHY PLL series:
