From: Fabien Parent <fparent@xxxxxxxxxxxx>
Enable USB Type-C support on MediaTek MT8395 Genio 1200 EVK by adding
configuration for TCPC Port, USB-C connector, and related settings.
Configure dual role switch capability, set up PD (Power Delivery) profiles,
and establish endpoints for SSUSB (SuperSpeed USB).
Update pinctrl configurations for U3 P0 VBus default pins and set dr_mode
to "otg" for OTG (On-The-Go) mode operation.
