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 DRA72x and AM57xx EVMs the card detect gpio is designed as active low gpio. So correcting the dt card detect gpio definition. Also adding card-detect gpio for DRA74x EVM. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
