Subject: [PATCH 4/4] soc: qcom: pmic_glink: properly describe the DP connector

During the discussion of the DP connectors, it was suggested that USB-C
DisplayPort connectors should have DRM_MODE_CONNECTOR_DisplayPort
connector type. This follows the example provided by other drivers
(AMDGPU, Intel). To distinguish them from native DP ports, they should
have the freshly defined USB as a subconnector type.
