Thanks Johan for the fixes.

The receiver should not be enabled until the port is opened so drop the
bogus call to start rx from the setup code which is shared with the
console implementation.
This was added for some confused implementation of hibernation support,
but the receiver must not be started unconditionally as the port may not
have been open when hibernating the system.

Does it mean hibernation will break now ? Not sure if its tested with
hibernation. I can see this call was added to port_setup specifically
for hibernation but now after removing it, where is it getting fixed ?
I think RX will not be initialized after hibernation.
port->setup = true;
