Laurent Pinchart b6c5ef6f6d serial: sh-sci: Make probe fail for ports that exceed the maximum count ...

The driver supports a maximum number of ports configurable at compile
time. Make sure the probe() method fails when registering a port that
exceeds the maximum instead of returning success without registering the
port.

This fixes a crash at system suspend time, when the driver tried to
suspend a non-registered port using the UART core.
