In case of problems when initializing the chip, the error flows aren't
being properly done. Specifically, it's possible that the chip would be
left in a configuration allowing it [internally] to access the host
memory, causing fatal problems in the device that would require power
cycle to overcome.

This patch moves the qed* driver into utilizing the 8.7.3.0 FW.
This new FW is required for a lot of new SW features, including:
  - Vlan filtering offload
  - Encapsulation offload support
  - HW ingress aggregations
As well as paving the way for the possibility of adding storage protocols
in the future.

V2:
 - Fix kbuild test robot error/warnings.

When using INTa, ISR might be called before device is configured
for INTa [E.g., due to other device asserting the shared interrupt line],
in which case the ISR would read the SISR registers that shouldn't be
read unless HW is already configured for INTa. This might break interrupts
later on. There's also an MSI-X issue due to this difference, although
it's mostly theoretical.

This patch changes the initialization order, calling request_irq() for the
slowpath interrupt only after the chip is configured for working
in the preferred interrupt mode.

Physical link is handled by the management Firmware.
This patch lays the infrastructure for attention handling in the driver,
as link change notifications arrive via async. attentions,
as well the handling of such notifications.

This patch also extends the API with the protocol drivers by adding
registered callbacks which the protocol driver passes to qed in order
to be notified of async. events originating from the FW/HW.

The Qlogic Everest Driver is the backend module for the QL4xxx ethernet
products by Qlogic.

This module serves two main purposes:
 1. It's responsible to contain all the common code that will be shared
    between the various drivers that would be used with said line of
    products. Flows such as chip initialization and de-initialization
    fall under this category.

 2. It would abstract the protocol-specific HW & FW components, allowing
    the protocol drivers to have a clean APIs which is detached in its
    slowpath configuration from the actual HSI.

This adds a very basic module without any protocol-specific bits.
I.e., this adds a basic implementation that almost entirely falls under
the first category.
