[PATCH] ARM: dts: at91: sama5d27_som1_ek: enable ADC node

From: Eugen Hristev <hidden>
Date: 2021-06-22 10:18:08 

Enable the ADC for AN pins on Mikrobus1 and Mikrobus2 on the board.
These correspond to channels AD6 and AD7 in the controller.

 # cat /sys/bus/iio/devices/iio\:device0/in_voltage6_raw
 240
 # cat /sys/bus/iio/devices/iio\:device0/in_voltage7_raw
