From: Bin Meng <bin.meng@windriver.com>

commit 298d03c2d7f1b5daacb6d4f4053fd3d677d67087 upstream.

Per HiFive Unmatched schematics, the card detect signal of the
micro SD card is connected to gpio pin #15, which should be
reflected in the DT via the <gpios> property, as described in
Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt.
