[PATCH 14/19] usb: ehci-mx6: Pass MISC address to usb_oc_config()

Instead of passing ad-hoc sequence number to usb_oc_config(), pass in
the USB MISC address itself. The USB MISC address comes from DT in DM
case, and from the old method using controller index in non-DM case.
Fixes: 4de51cc25b5 ("usb: ehci-mx6: Drop assignment of sequence number")
