Based on kernel commit 3c9a9f7fb0ee ("net/phy: micrel: Be more const
correct") by Jaeden Amero <jaeden.amero@ni.com>:
In a few places in this driver, we weren't using const where we could
have. Use const more.
In addition, change the arrays of strings in ksz9031_config_init() to be
not only const, but also static.
