USB: EHCI: remove PCI assumption
This patch (as1405) fixes a small bug in ehci-hcd's isochronous
scheduler. Not all EHCI controllers are PCI, and the code shouldn't
assume that they are. Instead, introduce a special flag for
controllers which need to delay iso scheduling for full-speed devices
beyond the scheduling threshold.
