dt-bindings: iio: adc: ad7192: Add clock provider
Internal clock of AD719X devices can be made available on MCLK2 pin. Add clock provider to support this functionality when clock cells property is present. The clock source can be either provided externally or the internal clock is used. Pair of clocks and clock-names property is mutally exclusive with #clock-cells property. Modify second example to showcase the mode where internal clock is used.
