This series aims to fix invalid mac address issue raised by Thiery Heiko
([1]). 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.
