The initial MAC address is retrieved from hardware if it's not
provided by device-tree. The reserved MAC address from hardware
will be used if non-reserved MAC address is invalid. It will
cause mismatched MAC address seen by hardware and software.
This disallows using the reserved hardware MAC address to avoid
the mismatched MAC address seen by hardware and software.
