usb: typec: constify the struct device_type usage
Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move all the
device_type variables in use by the driver to be constant structures as
well, placing it into read-only memory which can not be modified at
runtime.
