imx6q-sabrelite: Re-add mmc aliases

In commit d0399a46e7cda63c07e3eb8558bef84cfb068028, the device tree was
synchronized from linux and the aliases were dropped.

They need to be kept so that the mmc cards are in the right order.
Without the aliases, u-boot reports:
MMC:   FSL_SDHC: 2, FSL_SDHC: 3

With the aliases, u-boot reports:
MMC:   FSL_SDHC: 0, FSL_SDHC: 1

The upstream linux device tree does not contain the same aliases than
u-boot (It keeps the devices order with /dev/mmcblk2 and /dev/mmcblk3).
Because this board has been using different aliases in u-boot
and linux, a imx6q-sabrelite-u-boot.dtsi file is added to be
automatically included in imx6q-sabrelite.dts.

This way, linux and u-boot each keep their own aliases and there
is no breakage on current installations.

This should never be done for new boards as we want to keep linux and
u-boot with the same aliases as much as possible.
This patch is only necessary to avoid breaking existing setups.

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

usb: xhci: Fix root hub descriptor

When a system has multiple XHCI controllers, some of the
properties described in the descriptor of the root hub (such as
the number of ports) might differ between controllers.  Fix this
by switching from a single global hub descriptor to a hub
descriptor per controller.

mkimage: fit: Support signed configurations in 'auto' FITs

Extend support for signing in auto-generated (-f auto) FIT. Previously,
it was possible to get signed 'images' subnodes in the FIT using
options -g and -o together with -f auto. This patch allows signing
'configurations' subnodes instead of 'images' ones (which are hashed),
using option -f auto-conf instead of -f auto. Adding also -K <dtb> and
-r options, will add public key to <dtb> file with required = "conf"
property.

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.

        -k /folder/with/key-files -g keyname -o sha256,rsa4096 \
        -K u-boot.dtb -r kernel.itb

Example: Add public key with required = "conf" property to u-boot.dtb
without needing to sign anything. This will also create a useless FIT
named unused.itb.
