[ Upstream commit 9bbce32a20d6a72c767a7f85fd6127babd1410ac ] Without DT aliases, the numbering of mmc interfaces is unpredictable. Adding them makes it possible to refer to devices consistently. The popular suggestion to use UUIDs obviously doesn't work with a blank device fresh from the factory. See commit fa2d0aa96941 ("mmc: core: Allow setting slot index via device tree alias") for more discussion.
