serial: group all the 8250 related code together
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.

- Say Y here if you have dumb serial boards other than the four
- standard COM 1/2/3/4 ports. This may happen if you have an AST
- FourPort, Accent Async, Boca (read the Boca mini-HOWTO, available
- from <http://www.tldp.org/docs.html#howto>), or other custom
- serial port hardware which acts similar to standard serial port
- hardware. If you only use the standard COM 1/2/3/4 ports, you can
- say N here to save some memory. You can also say Y if you have an
- "intelligent" multiport card such as Cyclades, Digiboards, etc.
