Due to board-specific hardware constraints particularly related
to level shifter in this case the maximum frequency for SD High-Speed
(HS) mode must be limited to 37.5 MHz to ensure reliable operation of SD
card in HS mode.

This is achieved by introducing the `max-sd-hs-hz` property in the
device tree, allowing the controller to operate within safe frequency
limits for HS mode.
Probably we will now replicate the same discussion... And it will be
happening every time you send the same and not reflect it in commit msg.

Bindings say board setup, this commit msg says board config, but the
patch says SoC. This is not correct.

Best regards,
