[PATCH] net: mv88e6xxx: add missing SMI address init

[Marek Mojík]

Driver does not currently initialize the smi_addr field, but instead keeps
the default value. This leads to issues on systems with different hardware
configuration. We can fix this problem by reading the SMI address from
device tree.
