The micro SD card slot uses GPIO3_13 as card detect pin, so describe
it in the devicetree.
This was noticed when converting imx53-qsb board to driver model
in U-Boot as the micro SD card was not getting detected.
After this change it is possible to load the dtb and zImage
from the SD card and boot Linux.
