ARM: dts: stm32: Enable SDIO controller on stm32f469 disco board
This patch adds SDIO-related DT nodes required by stm32f469 board There is a hardware issue on these boards, it misses a pullup on the GPIO line used as card detect to allow correct SD card detection. To allow correct card detection "broken-cd" property is used.
