ARM: dts: stm32: Reinstate card detect behavior on ST boards

The cd-gpios with (GPIO_ACTIVE_LOW | GPIO_PULL_UP) gpio is thus far
unsupported, reinstate the old cd-gpios behavior until this handling
is fully implemented. This avoid potential issue for SDCard boot:
the card detect fails with floating gpio.
