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

Per HiFive Unleashed schematics, the card detect signal of the micro SD card is connected to gpio pin andy-shev#11, which should be reflected in the DT via the <gpios> property, as described in Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt.
