soc: qcom: pmic_glink: fix connector type to be DisplayPort

[ Upstream commit f86955f2b1ff9fbc7ae4f6595112b2f896885366 ]

As it was pointed out by Simon Ser, the DRM_MODE_CONNECTOR_USB connector
is reserved for the GUD devices. Other drivers (i915, amdgpu) use
DRM_MODE_CONNECTOR_DisplayPort even if the DP stream is handled by the
USB-C altmode. While we are still working on implementing the proper way
to let userspace know that the DP is wrapped into USB-C, change
connector type to be DRM_MODE_CONNECTOR_DisplayPort.
