Subject: [PATCH 4/5 v4] USB: enclose all depends on USB_OHCI_HCD within an if USB_OHCI_HCD block

This patch removes the various depends on USB_OHCI_HCD from the OHCI HCD
drivers and enclose them within an if USB_OHCI_HCD / endif block. The
Octeon OHCI HCD driver has been moved around to remain in this block.

Acked-by: Alan Stern <stern@...land.harvard.edu>
