[BNX2]: Add link-down workaround on 5706 serdes.
In some blade systems using the 5706 serdes, the hardware sometimes does not properly generate link down interrupts. We add a workaround in the driver's timer to force a link-down when some PHY registers report loss of SYNC. The parallel detect logic is cleaned up slightly to better integrate the workaround.
