It's called namespace. If platform serial ports are different, then
they have to have a separate namespace otherwise things like
console= end up having to have a separate namespace from the one
which the user sees in the filesystem.
Moreover, you introduce a bunch of special cases into the 8250 serial
driver - or you simply exclude the 8250 serial driver being used on a
platform.
