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.
