Short series to cleanup AFU interrupt allocation for opencapi.
Current code was using its own allocation service, calling opal
directly to get the trigger page. This is not needed and we can use
xive to achieve the same thing. The only caveat is that the trigger
page address is only valid after the interrupt has been mapped, but
that is not a problem with the way the code is using it.
No functional change.
Changelog:
v2:
