No. The property may be present in the device tree when running under
Freescale hypervisor and it is used to skip the MSI nodes which are not
mapped in PAMU.
The code in kernel handles both situations: when the property is present
and in this case it searches only the corresponding MSI device for
available interrupts and when the property is not present and in this
case it loops over all the MSI devices.
