[PATCH 2/4] dt-bindings: iio: adc: adi,ade9000: add adi,ade9430 compatible

[Antoniu Miclaus <antoniu.miclaus@analog.com>]

The ADE9430 is a polyphase energy metering device from the same family as
the ADE9000. It is register-compatible with the ADE9000 but does not
provide the on-chip dip/swell detection, and it has no on-chip digital
integrator (it relies on an external analog integrator for Rogowski coil
current sensors).

Add the new compatible. No spi-max-frequency constraint is needed as the
ADE9430 supports the same 20 MHz maximum SPI clock as the ADE9000.

-  The ADE9000 and ADE9078 are highly accurate, fully integrated, multiphase
-  energy and power quality monitoring devices. Superior analog performance and a
-  digital signal processing (DSP) core enable accurate energy monitoring over a
-  wide dynamic range. An integrated high end reference ensures low drift over
-  temperature with a combined drift of less than ±25 ppm/°C maximum for the
-  entire channel including a programmable gain amplifier (PGA) and an
-  analog-to-digital converter (ADC). The ADE9078 does not provide the on-chip
-  dip/swell detection available on the ADE9000.
