As per mmc device tree binding documentation card detect gpio has to be active low signal. When a hardware is designed with active high card detect, gpio polarity has to be changed with cd-inverted dt property.
In AM335x the card detect gpio is designed as active low gpio. So correcting the dt card detect gpio definition.
