Previously, speakup would always read the non-scrolled part of the VT,
even when the VT is scrolled back with shift-page. This patch makes
vt.c export screen_pos so that speakup can use it to properly access
the content of the scrolled-back VT.

Commit f79b0d9c22 ("staging: speakup: Fixed warning <linux/serial.h>
instead of <asm/serial.h>") broke the port information in the speakup
driver: SERIAL_PORT_DFNS only gets defined if asm/serial.h is included,
and no other header includes asm/serial.h.
We here make sure serialio.c does get the arch-specific definition of
SERIAL_PORT_DFNS from asm/serial.h, if any.
Along the way, this makes sure that we do have information for the
requested serial port number (index)

As the function documentation for tty_ldisc_ref_wait() notes, it is
only callable from a tty file_operations routine; otherwise there
is no guarantee the ref won't be NULL.
The key difference with the VT's paste_selection() is that is an ioctl,
where __speakup_paste_selection() is completely async kworker, kicked
off from interrupt context.

Architectures may only provide {cmp,}xchg_relaxed definitions in

linux/atomic.h, which means simply including asm/cmpxchg.h may not get
the definitions of all the{cmp,}xchg variants.
