Changes since v1:
- dropped RFC status as "this seems like the sort of feature somebody might reasonably want to use -- if they know exactly what they're doing";
- new preparatory patch (1/2) which moves already-in-there sysfs code into ehci-sysfs.c;
- moved uframe_periodic_max parameter from module option to sysfs attribute, so that it can be set per controller and at runtime, added validity checks;
- clarified a bit bandwith analysis for 96% max periodic setup as noticed by Alan Stern;
- clarified patch description saying that set in stone 80% max periodic is specified by USB 2.0;
