iio: accel: adxl355: use fwnode_irq_get_byname()
...
Use the generic fwnode_irq_get_byname() in place of of_irq_get_byname()
to get the IRQ number from the interrupt pin.

iio:accel:adxl355: Move exports into IIO_ADXL355 namespace
...
To avoid unnecessary pollution of the global symbol namespace move the
driver core exports into their own namespace and import that into the two
bus modules.

iio: accel: adxl355: Add triggered buffer support
...
Provide a way for continuous data capture by setting up buffer support. The
data ready signal exposed at the DRDY pin of the ADXL355 is exploited as
a hardware interrupt which triggers to fill the buffer.
