Add system wakeup capability over UART RX line for wakeup capable UART.
When system is suspended, RX line act as an interrupt to wakeup system
for any communication requests from peer.

One question below.

Should this order be swapped? Usually remove is done in reverse of probe
order, so clear_wake_irq, init wakeup, and remove uart port. I'm not
convinced it will actually matter though so maybe this isn't a problem.
Ok, I will update the order here.
