TTY: isdn, remove callout
I wonder how this survived there during the whole 2.6 series until now :D. Callouts are not used for a decade, so let us remove it also from isdn. This means removal of ISDN_ASYNC_CALLOUT_ACTIVE which is never raised in info->flags and callout_termios which are never used. This will help us to get rid of ISDN_ASYNC_* flags and use ASYNC ones from serial.h. And then we will switch to tty_port.
