[PATCH v3] arm64: dts: qcom: lemans-evk: Add OTG support for primary USB controller

[Krishna Kurapati <krishna.kurapati@oss.qualcomm.com>]

Enable OTG support for primary USB controller on EVK Platform. Add
HD3SS3220 Type-C port controller present between Type-C port and SoC
that provides role switch notifications to controller.

Signed-off-by: Krishna Kurapati <krishna.kurapati@oss.qualcomm.com>
