Previously a device which attempted to wake a sleeping host would not be notified about the resumed operation and thus stay suspended for ever. This is due to the fact that only a host initiated wakeup would trigger a interrupt. As a workaround we use the SOF interrupt which is enabled for a short amount of time to detect the resume of the bus and wakeup the device.
Leftover Sonix reference code cleanup. Sometimes when there is traffic on more than 1 ep's packets would be dropped before they could be handled. Clearing the status flags after handling them takes care of it.
