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;
