net: qrtr: Make wakeup timeout configurable 



The qrtr driver can guarantee that the packet gets queued to the socket
but cannot guarantee the client process will get time to run if auto
sleep is enabled. This config will help mitigate missed packets on
systems where auto sleep is too aggressive.

Use the pm_wakeup_ws_event() api so a hard wakeup can be specified.
This will ensure a resume occurs if the data coming in happens while
the device is going into suspend.
