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: 1. Moving the existing SD card configuration into a dedicated overlay. 2. Adding a new overlay to support eMMC. 3. 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.
