Sam Bobroff 00bc509554 vfio-pci/nvlink2: Allow fallback to ibm,mmio-atsd[0] ... Older versions of skiboot only provide a single value in the device tree property "ibm,mmio-atsd", even when multiple Address Translation Shoot Down (ATSD) registers are present. This prevents NVLink2 devices (other than the first) from being used with vfio-pci because vfio-pci expects to be able to assign a dedicated ATSD register to each NVLink2 device. However, ATSD registers can be shared among devices. This change allows vfio-pci to fall back to sharing the register at index 0 if necessary.
