ARM: dts: aspeed: Add ADC for AST2600 and enable for Rainier and Everest
Add the ADC nodes to the AST2600 devicetree. Enable ADC1 for Rainier and
Everest systems and add an iio-hwmon node for the 7th channel to report
the battery voltage.
Tested on Rainier:
~# cat /sys/class/hwmon/hwmon11/in1_input
