From: Bin Meng <bin.meng@windriver.com>
commit 6331b8765cd0634a4e4cdcc1a6f1a74196616b94 upstream.
Per HiFive Unleashed schematics, the card detect signal of the micro SD card is connected to gpio pin #11, which should be reflected in the DT via the <gpios> property, as described in Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt.
