Merge branch 'qed-Advance-to-FW-8.33.1.0'

Tomer Tayar says:

====================
qed*: Advance to FW 8.33.1.0

This series advances all qed* drivers to use firmware 8.33.1.0 which brings
new capabilities and initial support of new HW. The changes are mostly in
qed, and include changes in the FW interface files, as well as updating the
FW initialization and debug collection code. The protocol drivers have
minor functional changes for this firmware.

Patch 1 Rearranges and refactors the FW interface files in preparation of
the new FW (no functional change).
Patch 2 Prepares the code for support of new HW (no functional change).
Patch 3 Actual utilization of the new FW.
Patch 4 Advances drivers' version.

v3->v4:
Fix a compilation issue which was reported by krobot (dependency on CRC8).

v2->v3:
Resend the series with a fixed title in the cover letter.

v1->v2:
- Break the previous single patch into several patches.
- Fix compilation issues which were reported by krobot.
