3.19.8-ckt16 -stable review patch.  If anyone has any objections, please let me know.

From: Florian Fainelli <f.fainelli at gmail.com>

commit 258bf44364263cb6391f35ebaca3c2366655bded upstream.

Since we were wrongly advertising gigabit features for these 10/100 only
Ethernet PHYs, bcm7xxx_config_init() which is supposed to apply workaround
would have not run since the check would be true, now that we have fixed the
PHY features, remove that check since it has no reasoning to be there anymore.
