[PATCH 2/4] dt-bindings: iio: adc: adi,ade9000: add adi,ade9039 compatible

[Antoniu Miclaus]

The ADE9039 is a polyphase energy metering device from the same family as
the ADE9000. It is register compatible with the ADE9000 for everything the
driver uses, provides the same on-chip dip/swell detection, and shares the
full-scale codes of the ADE9078.

It computes only fundamental reactive power and has no total reactive power
register, which is noted in the description. Like the ADE9078 it supports a
maximum serial clock frequency of 10 MHz rather than 20 MHz, so extend the
existing spi-max-frequency constraint to cover it.

 description: |
-  The ADE9000, ADE9078 and ADE9430 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 and ADE9430 do not
-  provide the on-chip dip/swell detection available on the ADE9000, and the
-  ADE9430 has no on-chip digital integrator (it uses an external analog
-  integrator for Rogowski coils).
