Subject: [PATCH v1 1/1] iio: adc: mxs-lradc-adc: Get rid of OF specifics

First of all, the additional conversion from vIRQ, and this is exactly
what is returned by platform_get_irq_byname(), to vIRQ is not needed.
Hence, drop no-op call to irq_of_parse_and_map().

Second, assign the firmware node instead of of_node.
