As discussed, the recipe changes for FIT configs would ensure that SD card
overlay is picked by default as per the default DIP switch configuration on the
board.
However, due to conflicting properties and dtso limitations, SD card properties
couldn't be added as default in the SoC DT, therefore shifing it to the platform
file for better handling.
