changes in v6:
- fix title: remove "driver" from "High Performance, Polyphase Energy Metering driver"
- improve interrupt-names property: change from free-form description to proper enum schema
with items/enum structure and minItems constraint

+description: |
+ The ADE9000 is a highly accurate, fully integrated, multiphase energy and power
+ quality monitoring device. 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).
