description:
Fixes a problem that the attach function reported
"wm_gmii_setup_phytype: Unknown PHY model. OUI=000000, model=0000" and
"PHY type is still unknown." Don't call wm_gmii_setup_phytype() three times if
the interface uses SGMII with internal MDIO.

 Tested with I354(Rangeley(SGMII(MDIO))) and I350(SERDES(SFP), SGMII(SFP)).
