ARM: dts: dra7xx: am57xx: 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 DRA74x, DRA72x and AM57xx EVMs the card detect gpio is
designed as active low gpio. So correcting the dt card detect
gpio definition.
