Subject: [PATCH] arm64: dts: qcom: lemans-evk: Add host mode support for USB1 controller

Enable Host mode support for USB1 controller on EVK Platform.

For secondary USB Typec port, there is a genesys USB HUB sitting in between
SOC and HD3SS3220 Type-C port controller and SS lines run from the SoC
through the hub to the Port controller. Mark the second USB controller as
host only capable.

Added HD3SS3220 Type-C port controller along with Type-c connector for
controlling vbus supply.
