The uhci1, uhci2, uhci3 companion controllers for ehci1 must
have a master start port set. Since this value is predictable
we should set it automatically if the app does not supply it
(cherry picked from commit 03b804a200)
(crobinso: Drop an element that wasn't backported to -maint branch.)
Currently each USB2 companion controller gets put on a separate
PCI slot. Not only is this wasteful of PCI slots, but it is not
in compliance with the spec for USB2 controllers. The master
echi1 and all companion controllers should be in the same slot,
with echi1 in function 7, and uhci1-3 in functions 0-2 respectively.
