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.
