Return boolean from ->carrier_raised() instead of 0 and 1. Make the
return type change also to tty_port_carrier_raised() that makes the
->carrier_raised() call (+ cd variable in moxa into which its return
value is stored).

Also cleans up a few unnecessary constructs related to this change:

	return xx ? 1 : 0;
	-> return xx;

	if (xx)
		return 1;
	return 0;
	-> return xx;

Same here, please split out the USB serial changes except for the
actual tty-port op change in usb-serial.c.

You can submit a follow-up series for USB serial as those changes are
otherwise unrelated to the changed tty-port interface.
