imx6qdl-sabresd: Pass mmc alias

After the sync with Linux in commit c2092e38fd66 ("imx6dl/imx6qdl:

the upstream version does not have it.
This causes a regression in which the SD 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 SD card (esdhc3) was

First, to quote the author:
This series adds support for the PCIe controller found on Apple M1 and
M2 machines and enables support for PCIe XHCI controllers. This makes
the type-A USB ports on the M1 Mac mini work. Since the use of Apples
DART IOMMU is mandatory (these PCIe DARTs don't support bypass mode),
this adds DMA mapping operations to the IOMMU uclass and implements
them for the Apple DART. It modifies the XHCI driver code to go map
DMA buffers through the IOMMU if there is one. Since the M1 Mac mini
now has two types of XHCI controllers with different number of ports
(2 for the DWC3 controllers, 8 for the Fresco Logic PCIe controller)
this uncovered an issue in with the way the hub descriptor is
implemented in the XHCI driver.
Second, Mark also fixes some Apple-specific instances of
CONFIG_IS_ENABLED that should be IS_ENABLED.

using option -f auto-conf instead of -f auto. Adding also -K <dtb> and

Summary:
-f auto => FIT with crc32 images
-f auto -g ... -o ... => FIT with signed images
-f auto-conf -g ... -o ... => FIT with sha1 images and signed confs
Example: FIT with kernel, two device tree files, and signed
configurations; public key (needed to verify signatures) is
added to u-boot.dtb with required = "conf" property.
