Right. I guess each real pin manipulation will be handled like sci_init_pins().
On the other hand, I don't think there is much things to do here for channels
that does *not* support control lines. get_mctrl() does not provide the function
to tell "not supported" condition anyway.

I think that should be implemented in sci_set_termios().
Currently, it sets SCFCR.MCE regardless of the HW function, and does not
fix any bits in c_flags. We can negate CRTSCTS in termios->c_cflag there,
unless (s->cfg->flags & UPF_xx) or something.
Does anyone know good flags or constant definitions?
