Key is trimmed to what the system and ecosystem needs.

Do we need 10 serial aliases? There are'nt 10 serial ports exposed in
j782s2. ok - lets say we do this, then: [1] is needed to boot? but why
do we need to do that for all armv8 platforms when aliases allows us
to trim it to just the 3 or 4 serial ports the platform really needs
That + being able to use the convention that serial2 is always linux
console, is'nt that a good thing? Hence recommending to just expose the
serialports as aliases to exactly what we need while keeping serial2 as
the linux console (which in this case happens to be main_uart8 - example
as j721s2 does).
