[PATCH] ARM: dts: stm32: Temporarily drop cd-gpios from AV96 DT

The card-detect GPIO and any other GPIO access currently doesn't work in U-Boot SPL on any STM32 platform and crashes the SPL. To work around this problem on AV96 right before release, remove the cd-gpios from DT. This patch must be reverted right after release, once the proper fix for the GPIO driver, "gpio: stm32: support gpio ops in SPL", is applied.
