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

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
