ARM: dts: imx7d-sdb-u-boot: Fix usdhc1 UHS operation
Commit 1a7904fdfa7d ("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.
