This is the last traces of pausing I/O that we had back some
twenty years ago. Probably was only required for 8MHz ISA
cards running "on the edge" at 12MHz. Anyway it hasn't been
in use for years, so lets just bury it for good.

There are multiple users of this file from different source
paths now, and rather than have ../ paths in include statements,
just move the file to the linux header dir.

Commit 9bef3d4197
"serial: group all the 8250 related code together"
inadvertently swept up the m32r driver in the move, because
it had comments mentioning 8250 registers within it. However
these are only there by nature of the driver being based off
the 8250 source code -- the hardware itself does not actually
have any relation to the original 8250 style UARTs.

On sparc, there is a build failure:
drivers/tty/serial/8250/8250.c:48:21: error: suncore.h: No such file or directory
drivers/tty/serial/8250/8250.c:3275: error: implicit declaration of function 'sunserial_register_minors'
drivers/tty/serial/8250/8250.c:3305: error: implicit declaration of function 'sunserial_unregister_minors'
this is due to commit 9bef3d4197
(serial: group all the 8250 related code together) moved these files
into 8250/ subdirectory, but forgot to change the reference
to drivers/tty/serial/suncore.h.

The drivers/tty/serial dir is already getting rather busy.
Relocate the 8250 related drivers to their own subdir to
reduce the clutter.
Note that sunsu.c is not included in this move -- it is
8250-like hardware, but it does not use any of the existing
infrastructure -- and does not depend on SERIAL_8250.
