We have an interrupt handler for the wake-up GPIO pin, but we're missing
the code to wake-up the system. This can cause timeouts receiving data
for the UART that shares the wake-up GPIO pin with the USB PHY.
All we need to do is just wake the system and kick the autosuspend
timeout to fix the issue.
