igb: add locking to reads of the i2c interface
The current implementation of sgmii support isn't correctly locking the
interfaces for reads/writes. This change pulls the read/write
functionality out of 82575.c and moves it to phy.c. In addition it
replaces the implementation in 82575.c with one that uses locking around
the relocated i2c interface calls.
