I saw this in the pull request, can this please be reverted?

Putting the aliases into the .dtsi file is really silly, as there are
likely boards that
don't connect every single one of those, and then will have to
override and renumber
them.

Please only list the aliases that are actually connected on a particular
board.

The mmc ones should probably go away as well.
