Misc updates from mlx5-next branch:
1) Add the required HW definitions and structures for upcoming TLS
support.
2) Add support for MCQI and MCQS hardware registers for fw version query.
3) Added hardware bits and structures definitions for sub-functions
4) Small code cleanup and improvement for PF pci driver.
5) Bluefield (ECPF) updates and refactoring for better E-Switch
management on ECPF embedded CPU NIC:
5.1) Consolidate querying eswitch number of VFs
5.2) Register event handler at the correct E-Switch init stage
5.3) Setup PF's inline mode and vlan pop when the ECPF is the
E-Swtich manager ( the host PF is basically a VF ).
5.4) Handle Vport UC address changes in switchdev mode.
6) Cleanup the rep and netdev reference when unloading IB rep.

Devlink eswitch mode is not necessarily related to SR-IOV, e.g, ECPF
can be at offload mode when SR-IOV is not enabled.
Rename the interface and eswitch mode names to decouple from SR-IOV,
and cleanup eswitch messages accordingly.

This series provides some low level updates for mlx5 driver needed for
both rdma and netdev trees.
1) Termination flow steering table bits and hardware definitions.
2) Introduce the core dump HW access registers definitions.
3) Refactor and cleans-up VF representors functions handlers.
4) Renames host_params bits to function_changed bits and add the
support for eswitch functions change event in the eswitch general case.
(for both legacy and switchdev modes).
5) Potential error pointer dereference in error handling

Currently for every representor type and for every single vport,
representer function pointers copy is stored even though they don't
change from one to other vport.
Additionally priv data entry for the rep is not passed during
registration, but its copied. It is used (set and cleared) by the user
of the reps.
As we want to scale vports, to simplify and also to split constants
from data,
1. Rename mlx5_eswitch_rep_if to mlx5_eswitch_rep_ops as to match _ops
prefix with other standard netdev, ibdev ops.
2. Constify the IB and Ethernet rep ops structure.
3. Instead of storing copy of all rep function pointers, store copy
per eswitch rep type.
4. Split data and function pointers to mlx5_eswitch_rep_ops and
mlx5_eswitch_rep_data.

Avoid typecasting from void* to mlx5_ib_dev* or mlx5e_rep_priv*
as it is not needed.

To avoid any ambiguity between vport index and vport number,
rename functions that had vport, to vport_num or vport_index appropriately.
vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return
type to u16.
vport_index is an int in vport array. Hence change input type of vport
index in mlx5_eswitch_index_to_vport_num() to int.
Correct multiple eswitch representor interfaces use type u16 of
rep->vport as type int vport_index.
Send vport FW commands with correct eswitch u16 vport_num instead
host int vport_index.

Currently the steering for SQs created on representors is done on
creation, once we move to representors as ports of an IB device we need
the port argument which is given only at the modify QP stage, adjust the
code appropriately.

IB driver maintains different registration and load function calls
for uplink and VF vports. This is not necessary as they only differ
with each other on their profiles.
This patch doesn't change any functionality.

This commit adds full support for IB representor:
1) Representors profile, We add two new profiles:
nic_rep_profile - This profile will be used to create an IB device that
represents the PF/UPLINK.
rep_profile - This profile will be used to create an IB device that
represents VFs. Each VF will be its own representor.
2) Proper load/unload callbacks, Those are called by the E-Switch when
moving to/from switchdev mode.
3) Different flow DB handling for when we in switchdev mode.

Currently we listen to netdev register/unregister event based on PCI
device. When in switchdev mode PF and representors share the same PCI
device, so in order to pair ib device and netdev in switchdev mode
compare the netdev that triggered the event to that of the representor.
Expose a function that lets you receive the netdev associated what
a given representor.

Create the basic infrastructure of registering and unregistering
IB representors. The load/unload callbacks are left empty and
proper implementation will be introduced in following patches.
