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.
