usb-ehci: Support interrupt transfers via periodic list
Interrupt transfers aren't meant to be used from the async list
(the EHCI spec indicates trouble with low/full-speed intr on async).
Build a periodic list instead, and provide an API to make use of it.
Then, use that API from the existing interrupt transfer API.
BUG=chrome-os-partner:5752
TEST=Use USB keyboard in u-boot (recovery mode) when later
commits make use of this code
