[PATCH v2 4/8] dt-bindings: iio: adc: adi,ad4030: Add PWM

[Marcelo Schmitt <marcelo.schmitt@analog.com>]

In setups designed for high speed data rate capture, a PWM is used to
generate the CNV signal that issues data captures from the ADC. Document
the use of a PWM for AD4030 and similar devices.

Signed-off-by: Marcelo Schmitt <marcelo.schmitt@analog.com>

Change log v1 -> v2
- Dropped pwm-names since only one PWM signal is directly requested by the ADC.
