[PATCH] usb: ohci-at91: Use dynamic device name for OHCI HCD creation

Use the dynamic device name instead of the hardcoded string "at91"
when creating the OHCI host controller driver.
This ensures that the device name is more flexible
and correctly reflects the actual device in the system.
This will be in sync with ehci at91 driver.
