net/mlx5: Support 4 ports VF LAG, part 1/2

This series continues the series[1] "Support 4 ports HCAs LAG mode"
by Mark Bloch. This series adds support for 4 ports VF LAG (single FDB
E-Switch).

This series of patches focuses on refactoring different sections of the
code that make assumptions about VF LAG supporting only two ports. For
instance, it assumes that each device can only have one peer.

Patches 1-5:
- Refactor ETH handling of TC rules of eswitches with peers.
Patch 6:
- Refactors peer miss group table.
Patches 7-9:
- Refactor single FDB E-Switch creation.
Patch 10:
- Refactor the DR layer.
Patches 11-14:
- Refactors devcom layer.

Next series will refactor LAG layer and enable 4 ports VF LAG.
This series specifically allows HCAs with 4 ports to create a VF LAG
with only 4 ports. It is not possible to create a VF LAG with 2 or 3
ports using HCAs that have 4 ports.

Currently, the Merged E-Switch feature only supports HCAs with 2 ports.
However, upcoming patches will introduce support for HCAs with 4 ports.

In order to activate VF LAG a user can execute:

devlink dev eswitch set pci/0000:08:00.0 mode switchdev
devlink dev eswitch set pci/0000:08:00.1 mode switchdev
devlink dev eswitch set pci/0000:08:00.2 mode switchdev
devlink dev eswitch set pci/0000:08:00.3 mode switchdev
ip link add name bond0 type bond
ip link set dev bond0 type bond mode 802.3ad
ip link set dev eth2 master bond0
ip link set dev eth3 master bond0
ip link set dev eth4 master bond0
ip link set dev eth5 master bond0

Where eth2, eth3, eth4 and eth5 are net-interfaces of pci/0000:08:00.0
pci/0000:08:00.1 pci/0000:08:00.2 pci/0000:08:00.3 respectively.

User can verify LAG state and type via debugfs:
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/state
/sys/kernel/debug/mlx5/0000\:08\:00.0/lag/type
