9043adee3e mx7dsabresd: Convert to watchdog driver model
Commit 68dcbdd594 ("ARM: imx: Add weak default reset_cpu()") caused
the 'reset' command in U-Boot to not cause a board reset.

Fix it by switching to the watchdog driver model via sysreset, which
is the preferred method for implementing the watchdog reset.

2f9b07d869 imx7d-sdb-u-boot: Pass SPDX-License tag
SPDX-License tag is missing and checkpatch complains about it.

Add the SPDX-License tag using the same one from imx7d-sdb.dts.

45651a3d69 imx7: Disable CAAM Job Ring 0
Trying to boot a fitImage after a successful hab_auth_img operation
causes the following error:

   Verifying Hash Integrity ... sha256Error in SEC deq
   CAAM was not setup properly or it is faulty error!

The reason for this error is that the BootROM uses the CAAM Job Ring 0,
so disable its node in U-Boot to avoid the resource conflict.

imx8m dtsi files also have the Job Ring 0 disable since the following
kernel commit:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch?h=v6.5&id=dc9c1ceb555ff661e6fc1081434600771f29657c

For a temporary solution, disable the Job Ring 0 in imx7s-u-boot.dtsi.

0aea5dda29 ARM: dts: imx7d-sdb-u-boot: Fix usdhc1 UHS operation
Commit 1a7904fdfa ("mmc: fsl_esdhc_imx: Use esdhc_soc_data
flags to set host caps") exposed the following SD card error:

U-Boot 2023.04-00652-g487e42f7bc5e (Apr 05 2023 - 22:14:21 -0300)

CPU:   Freescale i.MX7D rev1.0 1000 MHz (running at 792 MHz)
CPU:   Commercial temperature grade (0C to 95C) at 35C
Reset cause: POR
Model: Freescale i.MX7 SabreSD Board
Board: i.MX7D SABRESD in non-secure mode
DRAM:  1 GiB
Core:  100 devices, 19 uclasses, devicetree: separate
PMIC: PFUZE3000 DEV_ID=0x30 REV_ID=0x10
MMC:   FSL_SDHC: 0, FSL_SDHC: 1, FSL_SDHC: 2
Loading Environment from MMC... Card did not respond to voltage
select! : -110
*** Warning - No block device, using default environment

The reason of the problem, as explained by Ye Li:

"When UHS is enabled in defconfig, the usdhc1 node in imx7d-sdb.dts does
not configure pad for VSELECT, also the data pad should be set to
100Mhz/200Mhz pin states."

Apply these changes into u-boot.dtsi for now. When these changes
reach the Linux mainline imx7d-sdb, they can be dropped from u-boot.dtsi.

This fixes UHS mode on the imx7d-sdb board.
