extcon: usbc-tusb320: Call the Type-C IRQ handler only if a port is registered

commit 341fd15e2e18c24d5c738496cfc3d7a272241201 upstream. Commit bf7571c00dca ("extcon: usbc-tusb320: Add USB TYPE-C support") added an optional Type-C interface to the driver but missed to check if it is in use when calling the IRQ handler. This causes an oops on devices currently using the old extcon interface. Check if a Type-C port is registered before calling the Type-C IRQ handler.
