[BNX2X]: Correct Link management

Properly protect PHY access between two devices on the same board with
a HW lock.

Use GPIO to clear all previous configurations before changing link
parameters.

Shut down the external PHY in case of fan failure.

Reducing the MDC/MDIO clock to 2.5MHz due to problems with some
devices.

Resolve the flow control response according to autoneg with external
PHY.

Unmasking all PHY interrupts in single write to prevent a race in the
interrupts order.

LASI indication fixes to work with peculiarities of PHYs.

Disable MAC RX to avoid a HW bug when closing the MAC under traffic.

Disable parallel detection on HiGig due to HW limitation.

Updating the shared memory structure to work with the current
bootcode.
