[PATCH] serial: fix comments in 8250.c
Fix the formatting of some comments in 8250.c, and add a note that the
register_serial / unregister_serial shouldn't be used in new code.
We do this here in preference to adding to linux/serial.h, since that is used
by a number of non-8250 drivers which pretend to be 8250. It is not known
whether it would be appropriate to do so.
