This is a draft implementation of event notification mechanism from Simon. Under this scheme, any U-Boot subsystem can register some kind of callback function to a particular event (more event types will be added later) and that function will be invoked once the event is fired.
As a first user, UEFI subsystem makes use of PROBE and REMOVE events so that we will be able to automatically create/remove efi_disk objects relying on associated block devices (UCLASS_BLK).
To run the test: ./u-boot -T -c "ut common test_event_probe"

Should we split this into a few patches for submission? Also needs docs.
