ARM: dts: imx50-kobo-aura: Add Netronix embedded controller
Enable the Netronix EC on the Kobo Aura ebook reader.
Several features are still missing:
- Frontlight/backlight. The vendor kernel drives the frontlight LED
using the PWM output of the EC and an additional boost pin that
increases the brightness.
- Battery monitoring
- Interrupts for RTC alarm and low-battery events
