This updates the EHCI driver by adding an improved scheduler for the transaction translators, found in USB 2.0 hubs and used for low and full speed devices. - adds periodic_tt_usecs() and some helper functions, which does the same thing that "periodic_usecs" does, except on the other side of the TT, i.e. it calculates the low/fullspeed bandwidth usage instead of highspeed. - adds a tt_available() function which is the new implementation of what tt_no_collision() does ... while tt_no_collision() ensures that each TT handles only 1 periodic transfer at a time (a very pessimistic approach) this version instead tracks bandwidth and allows each TT to handle as many transfers as will fit on each TT's downstream bus (closer to best-case). The new scheduler is selected by a config option, marked as EXPERIMENTAL so it can be tested (and more broadly reviewed) for a while until it seems safe to remove the original scheduler.
