tg3: Abort phy init for 5717 serdes devices
The 5717 serdes devices have a different phy register layout than all
other previous serdes devices. This patch aborts the phy init sequence
in tg3_phy_reset() if the device is a 5717 serdes. It also aborts the
tg3_phy_toggle_apd() operation. Most other operations in the MII_SERDES
path are O.K.
