Introduce the split MT8195 laptop and iot USB configurations.
The hardware specifications for LAPTOP devices is different from IOT
devices. The major differences include some hardware constrains for
dual-role switch for USB controllers in different configurations,
especially for power management and other control flows as well.
Here are some hardware specifiction differences listed:
1. LAPTOP (Cherry Tomato boards) don't support USB gadget (device mode).
2. IOT devices must support multiple gadget devices and host mode.
3. Dual-role switch is not fully supported. Only USB PORT0 support
dual-role switch.
4. Power management is designed in primary and secondary dominator.
For a dual-role port, the device controller is the primary controller
for power management; while the host controller is the secondary.
LAPTOP devices should remove device nodes for avoiding abnormal
behavior.
This modifcation is to add USB configurations "mt8195-laptop-usb.dtsi"
for LAPTOP devices, and add "mt8195-iot-usb.dtsi" for IOT devices.
To remove common USB configurations for mt8195.dtsi and switch includes
dtsi these new files for the boards will come in next patch.
