[PATCH 1/8] dt-bindings: iio: adc: ad7606: Make corrections on spi conditions

The SPI conditions are not always required, because there is also a
parallel interface. The way used to detect that the SPI interface is
used is to check if the reg value is between 0 and 256.
There is also a correction on the spi-cpha that is not required when SPI
interface is selected, while spi-cpol is.
