[PATCH v2] arm64: dts: qcom: lemans-evk: Enable Display Port

[Prahlad Valluru]

From: Shashank Maurya <quic_ssmaurya@quicinc.com>

Lemans EVK board has two mini-DP connectors, connected to EDP0
and EDP1 phys. Other EDP phys are available on expansion
connectors for the mezzanine boards.
Enable EDP0 and EDP1 along with their corresponding PHYs.
