[PATCH] USB: EHCI and Freescale 83xx quirk

[PATCH] USB: EHCI and Freescale 83xx quirk

On the MPC834x processors the multiport host (MPH) EHCI controller has an
erratum in which the port number in the queue head expects to be 0..N-1
instead of 1..N.  If we are on one of these chips we subtract one from
the port number before putting it into the queue head.
