USB: ehci: minor ISO updates, always support split ISO
Small updates to the EHCI driver's ISO support: - Get rid of the Kconfig option for full speed ISO. It may not be perfect yet, but it hasn't appeared to be dangerous and pretty much every configuration wants it. - Instead of two places to disable an empty periodic schedule after an ISO transfer completes, just have one. - After the periodic schedule is disabled, we can short-circuit the schedule scan ... it can't possibly have more work to do. Assuming a typical config with split iso enabled, the only change in behavior should be almost unobservable: quicker termination of periodic scans when the schedule gets emptied.
