USB: UHCI: adjust zhaoxin UHCI controllers OverCurrent bit value

commit dddb342b5b9e482bb213aecc08cbdb201ea4f8da upstream.

OverCurrent condition is not standardized in the UHCI spec.
Zhaoxin UHCI controllers report OverCurrent bit active off.
In order to handle OverCurrent condition correctly, the uhci-hcd
driver needs to be told to expect the active-off behavior.
