Laurentiu Tudor 2a5bbb13cc pci: layerscape: add a way of specifying additional iommu mappings
In the current implementation, u-boot creates iommu mappings only
for PCI devices enumarated at boot time thus does not take into
account more dynamic scenarios such as SR-IOV or PCI hot-plug.
Add an u-boot env var and a device tree property (to be used for
example in more static scenarios such as hardwired PCI endpoints
that get initialized later in the system setup) that would allow
two things:
 - for a SRIOV capable PCI EP identified by its B.D.F specify
   the maximum number of VFs that will ever be created for it
 - for hot-plug case, specify the B.D.F with which the device
   will show up on the PCI bus
More details can be found in the included documentation:
