Add Kconfig and Makefile to build irdma driver.
Remove i40iw driver and add an alias in irdma.
Remove legacy exported symbols i40e_register_client
and i40e_unregister_client from i40e as they are no
longer used.
irdma is the replacement driver that supports X722.

mmiowb() is now implicit in spin_unlock(), so there's no reason to call
it from driver code. Redefine i40iw_mmiowb() to do nothing instead.

MSS change on active QPs is not supported. Store new MSS
value for new QPs only. Remove code to modify MSS on the fly.
This also resolves a crash on QP modify to QP 0.

Some resources are incorrectly organized and at odds with
HW capabilities. Specifically, ILQ, IEQ, QPs, MSS, QOS

Add support for QoS on QPs. Upon device initialization,
a map is created from user priority to queue set
handles. On QP creation, use ToS to look up the queue
set handle for use with the QP.

This patch replaces the obsolete crypto hash interface with shash
and resolves a build failure after merge of the rdma tree
which is caused by the removal of crypto hash interface
Removing CRYPTO_ALG_ASYNC from crypto_alloc_shash(),
because it is by definition sync only
