Some uclasses want to set up a device before it is probed. Add a method for this. An example is with PCI, where a PCI uclass wants to set up its private data for later use. This allows the device's uclass() method to make calls whcih use that data (for example, read PCI memory regions from device tree, set up bus numbers). Signed-off-by: Simon Glass <sjg@chromium.org>
