The use of mshc aliases is deprecated for some while,
so remove them from the rk3036.dtsi file.

I noticed that the alias property is still listed in the
documentation[1]. Could you please share where it has been formally
marked as deprecated? I may have missed the update.

[1] Documentation/devicetree/bindings/mmc/mmc-controller.yaml

Mshc aliases driver support was introduced 2018 in dw_mmc.c only and before that a undocumented copy paste entered somehow into dtsi files.
The mmc-controller.yaml file change in 2020 mentions a fixed index mmcN format.
A generic alias name "mmc" is now preferred instead of a "mshc" driver specific.

As suggested by Arnd Bergmann and others, the newly added mmc aliases
should be board specific

Thanks for these details. Then I'm fine with this patch.
