bnx2x: 8073 PHY changes

8073 PHY changes
The initial support we had for this PHY needs some serious changing. The
major change is that this PHY should be initialized only when the first
function is loaded and not for each function. The official SPI-ROM of
this PHY was released and it requires some changes in the initialization
code as well
