The lemans EVK board supports either eMMC or SD-card, but only one can be active at a time. Move the SDHC node for SD card into a dedicated device tree overlay. This decoupling allows the storage medium to be selected dynamically by applying the appropriate overlay for either SD card or eMMC support.

This series updates the device tree configuration for the LeMans EVK
board to support dynamic selection between SD card and eMMC storage.
The LeMans EVK hardware supports either an SD card or eMMC, but the
interfaces are mutually exclusive as they share the same controller and
resources. Previously, SD card support was hardcoded in the main device
tree, preventing easy switching to eMMC.
This series refactors the SDHC configuration by:
Moving the existing SD card configuration into a dedicated overlay.
Adding a new overlay to support eMMC.
Updating the common SDHC node in the SoC dtsi to include necessary
resources (clocks, register ranges) required by the eMMC configuration.
This allows the bootloader to apply the appropriate overlay based on the
desired storage medium.
