This commit adds support for ADC peripherals in the Zephyr port. As is typical for Zephyr, the ADC channel setup is done in the devicetree (typically using an overlay). This code requires ADC channels to be listed in the io-channels property of the zephyr,user root node. Signed-off-by: Ned Konz <ned@metamagix.tech>
