WILC1000 mac address is currently not set until device is opened, at which point firmware is loaded and started. This results in default mac address being 00:00:00:00:00:00. This series, based on an initial patch from Ajay, reads the MAC address from chip eFuse whenever we set the first interface (at probe time). To do so, we need to ensure that any bus communication is properly initialized, so the first commits slightly rearrange/fix initialization/registration order to allow to read MAC address properly. Based on the tests I did during this series adjustments, there are still a few corner cased not properly handled, especially when dealing with two interfaces on top of the same wphy, but it fixes at least the user-facing mac address for those interfaces so user space network managers are not confused anymore.
