For the last couple of years Linux kernel got rid of a few architectures
and many platforms. Hence some PORT_* definitions in the serial_core.h
become unused and redundant. Remove them for good.

Below are results via Debian Code Search.

Note, I excluded Linux kernel itself from the "user" and Hurd, which seems
to have Linux kernel v2.6 which is _provider_ of the definition(s).

ifdeffed, safe to remove.
