siemens: capricorn: set max-frequency for usdhc1
This is required since
commit aebb523a2381 ("mmc: mmc-uclass: Use max-frequency from device tree with default handling")
and the related patches of the same series.
The error observed without this change is:
Autobooting in 3 seconds, press "<Esc><Esc>" to stop
EXT_CSD[179], PARTITION_CONFIG:
BOOT_ACK: 0x0
BOOT_PARTITION_ENABLE: 0x1 (boot0)
PARTITION_ACCESS: 0x0 (user)
Loading from eMMC ...fit
U-Boot SPL 2026.01-4238dcfcbfe (Jan 09 2026 - 08:19:45 +0000)
For this example it's the following commands which does no longer work
for larger images:
ext4load mmc 0:1 0x88000000 boot/fitImage
On latest master branch the problematic commit gets reverted with
commit c4f5b1d4b037 ("Revert "mmc: mmc-uclass: Use max-frequency from device tree with default handling"")
but for v2026.01 this fix is still required. Maybe it's anyway a good
idea to have this property set explicitly.
