zephyr: use a chosen DT node to find ADC devices
This change adds a cros-ec,adc chosen node to the device tree, to be used
by the ADC shim to locate the device to which all analog channels are
bound (rather than assuming it is named adc0). It also makes the
configuration happen at compile-time, saving some runtime indirection and
failing faster (at build rather than runtime) if misconfigured.
