ARM: dts: am335x: fix cd-gpios definition as per hardware design and dt binding docs
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.
