ARM: dts: imx6ul-14x14-evk: Pass the "broken-cd" property
imx6ul-14x14-evk does not have a GPIO dedicated for reading the card detect pin on the eSDHC2 micro-SD port. Pass the "broken-cd" property to describe the absence of the card detect GPIO so that polling must be used. According to Documentation/devicetree/bindings/mmc/mmc-controller.yaml: broken-cd: $ref: /schemas/types.yaml#/definitions/flag description: There is no card detection available; polling must be used. Even though no error is oberved in the kernel, the lack of the 'broken-cd' property caused the micro-SD to not be detected in U-Boot, so let's improve the device tree description to make it more accurate.
