Marek sent the same in the past:
https://lore.kernel.org/all/?q=%22exynos%3A+Use+fixed+index+for+the+MMC+devices%22

The patches are fine for me except, that these actually do not belong to
DTSI. Aliases for board or user-exposable interfaces are actually board
specific and each board should customize the ones it uses.
