Currently FF-A bus ffa_device_match() handles the workaround for the FF-A v1.0 devices which are not populated with UUID to match. The FF-A bus layer calls into FF-A driver and populates the device UUID if it matches with the driver attempting to match. But this forces to have both FF-A bus and core driver to be bundled into a single module. However, keep it as a single module adds problems for the FF-A driver registrations and their initcall levels. In preparation to split the FF-A bus and the core driver into distinct modules, we need to move the workaround away from the FF-A bus layer. We can add it into the FF-A core driver as a bus notifier. In order to do so, we need to always match any driver with the device if the UUID is NULL and then during the driver binding phase, we can populate the UUID if it matches with the driver UUID table using the bus notifiers. We also need to add a check for NULL UUID before calling the device/driver probe as devices with NULL UUID is possible since we match all for that case.
