riscv: dts: unleashed: Add gpio card detect to mmc-spi-slot

Browse Source 
commit 6331b8765c 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.
