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.

This device actually has a pair of interrupts. The code basically ignores

Whilst it is possible to output events to say buffers have passed
a particular level there are no obvious reasons to actually do so.
The upshot of this patch is that buffers will only ever have
one threshold turned on at a time.
For now sca3000 has it's ring buffer effectively disabled.
Fixed later in series.
