USB: OHCI: Export the OHCI hub control and status_data functions
Platform drivers sometimes need to perform specific handling of hub
control requests and status data. Make this possible by exporting the
ohci_hub_control() and ohci_hub_status_data() functions which can then
be called from custom hub operations in the default case.
