usb: hci: add hc_driver as argument for usb_hcd_pci_probe
usb_hcd_pci_probe expects users to call this with driver_data set as
hc_driver, that limits the possibility of using the driver_data for
driver data.
Add hc_driver as argument to usb_hcd_pci_probe and modify the callers
ehci/ohci/xhci/uhci to pass hc_driver as argument and freeup the
driver_data used
Tested xhci driver on Dragon-board RB3, compile tested ehci, ohci and
uhci.
[For all but the xHCI parts]
