Originally, the mmc aliases node was present in imx6qdl-wandboard.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 regression in which the SD card cannot be found anymore:
Since commit the aliases node has been removed U-Boot 2022.10-00999-gcca41ed3d63f-dirty (Nov 03 2022 - 22:07:38 -0300)
CPU: Freescale i.MX6QP rev1.0 at 792 MHz Reset cause: POR DRAM: 2 GiB Core: 62 devices, 17 uclasses, devicetree: separate PMIC: PFUZE100 ID=0x10 MMC: FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2 Loading Environment from MMC... MMC: no card present *** Warning - No block device, using default environment
Fix it by passing the alias node in the u-boot.dtsi file to restore the original behaviour where the SD card (esdhc3) was mapped to mmc0.
