Mark any serial ports that aren't registered by the board files as disabled in the device-tree files.
In practice, none of the now-disabled ports ended up succeeding device probing because of the missing clock-frequency property. However, explicitly marking the devices disabled has the advantage of squashing the dev_warn() the failed probe causes, and documenting that we intend the port not to be used, rather than accidentally left out the property.
