This patch removes redundant 8250 port initialization macros and
replaces them by a single generic base-macro, which is specialized
as needed.

Sorry, we did not even know that this tag existed. We will add this in our
next patch series.

Also, please thin out the Cc list, I would recommend remove just
ordinary commiters (with maybe few exceptions) and leave maintainers. 
Moreover some addresses are bounced.
