[U-Boot] [PATCH 027/126] pci: sandbox: Probe PCI emulation devices when used

At present PCI emulation devices are not probed before use, since they
used to be children of the device that used them, and children cannot be
probed before their parents.

Now that PCI emulation devices are attached to the root node, we can
simply probe them, and avoid using the internal function.
