ARM: dts: stm32: adopt generic iio bindings for adc channels on emstamp-argon

Browse source 
[ Upstream commit c46e9b6cc98245f7264a8d15394d1f95d433abec ]

Use STM32 ADC generic bindings instead of legacy bindings on
emtrion GmbH Argon boards.

The STM32 ADC specific binding to declare channels has been deprecated,
hence adopt the generic IIO channels bindings, instead.
The STM32MP151 device tree now exposes internal channels using the
generic binding. This makes the change mandatory here to avoid a mixed
use of legacy and generic binding, which is not supported by the driver.
