13cfac2038 staging:iio:adc:ad7606 conversion to irq_chip based polling.
I'm far from sure what the best way to handle this particular
part is, so have (I think) done the absolute minimum to change
it to the new interface.

V2: Trivial constification of device name.

Next patch will remove the current adis16350 driver.
These should have been merged a long time ago, but there we are.

V2: Move to single IIO_CHAN macro + use the new extend_name
to make the naming of the temperature sensors contain x, y, z
rather than messing with modifiers.  This a very weird case
and I don't want temperature to use axial modifiers.

d96d1337e3 staging:iio: Add infrastructure for irq_chip based triggers
V3: Get rid of separate interrupt pool. This is well handled
    by irq_get_descs and irq_free_descs.  Two functions I simply
    wasn't aware of previously.  Thus the allocation for a given
    trigger is now handled by core code rather than us reinventing
    the wheel.

V2: Stop silly name duplication.
    Move pool handling to industrialio-trigger as that is the only user.
    Changed over to using irq_modify_status rather than the arm
    specific set_irq_flags as per Thomas Gleixner's suggestion.
