    sys/dts: Add SD card overlays for the BananaPi-F3 SoC
    
    The K1 user manual lists three separate SDHCI devices but the
    upstream DTS file only defines the eMMC device.
    
    Create a temporary overlay to allow the BananaPi-F3 to boot from the
    SD card until this is addressed upstream.
