This patch contains register initialization related changes.
- Modifications to the runtime offsets - these are defines used
by the driver or firmware functions to set values that are used
by the initialization functions to set device register values.
- Global window values changes to provide different device register
ranges.
- Additional device registers addresses were added to the register file,
used in later stages.

This patch refactors the current llh implementation. It exposes a hw
resource called ppfid (port-pfid) and implements an API for configuring
the resource. Default configuration which was used until now limited
the number of filters per PF and did not support engine affinity per
protocol. The new API enables allocating more filter rules per PF and
enables affinitizing protocol packets to a certain engine which
enables full 100g protocol offload support.

In case of an attention from the doorbell queue block, analyze the HW
indications. In case of a doorbell overflow, execute a doorbell recovery.
Since there can be spurious indications (race conditions between multiple PFs),
schedule a periodic task for checking whether a doorbell overflow may have been
missed. After a set time with no indications, terminate the periodic task.

VFs are currently not mapping their doorbell bar, instead relying
on the small doorbell window they have in their limited regview bar.
In order to increase the number of possible Tx connections [queues]
employeed by VF past 16, we need to start using the doorbell bar if
one such is exposed - VF would communicate this fact to PF which would
return the size-bar internally configured into chip, according to
which the VF would decide whether to actually utilize the doorbell
bar.

This pushes qed [and as result, all qed* drivers] into using 8.20.0.0
firmware. The changes are mostly contained in qed with minor changes
to qedi due to some HSI changes.
Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, including:
- Corrects iSCSI fast retransmit when data digest is enabled.
- Stop draining packets when receiving several consecutive PFCs.
- Prevent possible assertion when consecutively opening/closing
many connections.
- Prevent possible assertion due to too long BDQ fetch time.
In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.

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.
