For AMD platform there is a requirement to enable user space role

DEVICE: echo device > /sys/class/usb_role/dwc3.0.auto-role-switch/role
A more important question that needs to be answered: why?
Our customer platform is not completely capable of OTG i.e with type C
controller it does not have PD to support role switching. Hence, they
have script which triggers the role switch based on ACPI/EC interrupt.
