This series extends PCIe Atomic Ops completer support to multifunction
vfio-pci devices. 
It is an update on previously discussed issues

Patch 1 refactors the existing atomic capability checking logic into
a reusable helper function.

Patch 2 extends the support to multifunction devices by calculating
the intersection of atomic capabilities across all functions, deferring
configuration to machine_done time when all functions are realized.

This extends commit c00aac6f14.
