ARM: dts: msm: Add UCSI connector to USB port on Parrot

Browse Source 
Add graph nodes representing the USB connector and its remote
endpoints to the UCSI device and the USB controller respectively.
Add 'usb-role-switch' properties to the DWC3 devices and update
its dual-role mode to 'otg'.
This is in order to describe a connection between the pmic_glink
and the DWC3 device to allow the former to notify the USB controller
when to start up in USB host or peripheral mode.
