Originally, the mmc aliases node was present in imx6qdl-pico.dtsi.
After the sync with Linux in commit d0399a46e7cd ("imx6dl/imx6qdl:
synchronise device trees with linux"), the aliases node is gone as
the upstream version does not have it.
This causes a boot regression in which the eMMC card cannot be found anymore.
Fix it by passing the alias node in the u-boot.dtsi file to
restore the original behaviour where the eMMC (esdhc3) was
mapped to mmc0.
Fixes: d0399a46e7cd ("imx6dl/imx6qdl: synchronise device trees with linux")
