This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.

This is mostly updates of the usual drivers: arcmsr, qla2xx, lpfc,
ufs, mpt3sas, hisi_sas. In addition we have removed several really
old drivers: sym53c416, NCR53c406a, fdomain, fdomain_cs and removed
the old scsi_module.c initialization from all remaining drivers. Plus
an assortment of bug fixes, initialization errors and other minor
fixes.

Current API between qed and protocol modules allows passing an
additional private string - but it doesn't get utilized by qed
anywhere.
Clarify the API by removing it and renaming it 'set_name'.

max_fin_rt is the maximum re-transmission of FIN packets

munmap done by iscsiuio during a stop of the service triggers a "bad
pte" warning sometimes. munmap kernel path goes through the mmapped
pages and has a validation check for mapcount (in struct page) to be
zero or above. kzalloc, which we had used to allocate udev->ctrl, uses
slab allocations, which re-uses mapcount (union) for other purposes that
can make the mapcount look negative. Avoid all these trouble by invoking
one of the __get_free_pages wrappers to be used instead of kzalloc for
udev->ctrl.

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.
Changes from previous version

Prepare to mark sensitive kernel structures for randomization by making
sure they're using designated initializers. These were identified during
allyesconfig builds of x86, arm, and arm64, with most initializer fixes
extracted from grsecurity.
For these cases, terminate the list with { }, which will be zero-filled,
instead of undesignated NULLs.
