[PATCH 0/2] ARM: dts: stm32: add SDIO pinctrl sleep support on stm32f7

Add support for switching the SDIO pins on the STM32F7 series to analog
mode when not in use to save power.

I don't have any of the disco/eval boards to test, but I have tested
this on an Emcraft STM32F746 SOM with a UCL-SOM-BSB carrier (using an
out-of-tree DT) and our custom carrier board.
