usb: typec: Remove retimers properly

Browse Source 
Retimer device class is left dangling when the typec module
is unloaded. Attempts to reload the module failed with warning:

        "sysfs: cannot create duplicate filename '/class/retimer'"

Fixing the issue by unregistering the class properly.
