[PATCH] spin longer for ehci port reset completion

This makes the EHCI driver spin a bit longer before concluding that the
port reset failed.  "Obviously safe."

It allows some devices to enumerate that previously didn't.  We've seen
a bunch of these problem reports recently, this will make some go away.

As reported by Michael Zapf <Michael.Zapf@uni-kassel.de>, some EHCI
controllers seem to take forever to finish port resets and produce
"port N reset error -110" type errors.  Spinning a bit longer helps.
