[PATCH v2] iio: adc: stm32-adc: Use dev_fwnode()

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().

So use the dev_fwnode() helper.
