FROMLIST: arm64: dts: qcom: lemans-evk: Move SD card support to overlay

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.
