[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.
