b7c1e069f5 dt-bindings: iio: adc: adi,ad4695: add SPI offload properties
Add a pwms property to the adi,ad4695 binding to specify an optional PWM
output connected to the CNV pin on the ADC.

Also add #trigger-source-cells property to allow the BUSY output to be
used as a SPI offload trigger source to indicate when a sample is ready
to be read.

Macros are added to adi,ad4695.h for the cell values to help with
readability since they are arbitrary values.

46e4ce4c11 dt-bindings: iio: ad4695: fix common-mode-channel
The common-mode-channel property is a scalar, not an array, so we should
not be using items: in the schema when specifying allowable values.
