In order to decouple ecam config space creation from probing via
pci_host_common_probe(), allow the private pointer to be populated
via the device drvdata pointer.

Crucially, this is set before calling ops->init(), allowing that
particular callback to have access to probe data.

This should have no impact on existing code which ignores the
current value of cfg->priv.
