Ilpo Järvinen b300fb26c5 tty: Convert ->carrier_raised() and callchains to bool ...

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;
