arm64: dts: mediatek: mt8395-genio-1200-evk: add support for TCPC port

Enable USB Type-C support on MediaTek MT8395 Genio 1200 EVK by adding
configuration for TCPC Port, USB-C connector, MUX IT5205 and related
settings.

Configure dual role switch capability, set up PD (Power Delivery) profiles,
and establish endpoints for SS (SuperSpeed) and HS (HighSpeed) USB.

Update pinctrl configurations for U3 P0 VBus default pins and set dr_mode
to "otg" for OTG (On-The-Go) mode operation.

Add ITE IT5205 (TYPEC MUX) under I2C2 bus and configure its properties;
also add references and configurations to 'typec-mux' node.
