USB: add RESET_RESUME device quirk

Browse Source 
This patch (as888) adds a new USB device quirk for devices which are
unable to resume correctly.  By using the new code added for the
USB-persist facility, it is a simple matter to reset these devices
instead of resuming them.  To get things kicked off, a quirk entry is
added for the Philips PSC805.
