tty: remove broken r3964 line discipline
Noone stepped up in the past two years since it was marked as BROKEN by commit c7084edc3f6d (tty: mark Siemens R3964 line discipline as BROKEN). Remove the line discipline for good. Three remarks: * we remove also the uapi header (as noone is able to use that interface anyway) * we do *not* remove the N_R3964 constant definition from tty.h, so it remains reserved. * in_interrupt() check is now removed from vt's con_put_char. Noone else calls tty_operations::put_char from interrupt context.

- This driver allows synchronous communication with devices using the
