Add attach/detach callbacks to interface API.
This is crucial for implementing seamless reset flow which releases the
hardware and it's resources upon detach while keeping software
structures and state (e.g netdev) then reset and reallocate the hardware
needed resources upon attach.

Simplify the code and makes it look modular and symmetric.
Split sriov enable/disable to two levels: device level and pci level.
When user enable/disable sriov (via sriov_configure driver callback) we
will enable/disable both device and pci sriov.
When driver load/unload we will enable/disable (on demand) only device
sriov while keeping the PCI sriov enabled for next driver load.
On internal/pci error, VFs will be kept enabled on PCI and the reset
is done only in device level.

Previous an_disable_cap position bit31 is deprecated to be use in driver
with newer firmware. New firmware will advertise the same capability
in bit29.
Old capability didn't allow setting more than one protocol for a
specific speed when autoneg is off, while newer firmware will allow
this and it is indicated in the new capability location.

This namespace is used for LAG demux flowtable.
The idea is to position the LAG demux ft between
bypass and kernel flowtables, allowing raw-eth

Available on dual port cards only, this feature keeps
track, using netdev LAG events, of the bonding
and link status of each port's PF netdev.
When both of the card's PF netdevs are enslaved to the
same bond/team master, and only them, LAG state
is active.
During LAG, only one IB device is present for both ports.
In addition to the above, this commit includes FW commands
used for managing the LAG, new facilities for adding and removing
a single device by interface, and port remap functionality according to
bond events.
Please note that this feature is currently used only for mimicking
Ethernet bonding for RoCE - netdevs functionality is not altered,
and their bonding continues to be managed solely by bond/team driver.

Exposed LAG commands enum and layouts:
- CREATE_LAG
HW enters LAG mode:
RoCE traffic from port two is received on PF0 core dev.
Allows to set tx_affinity (tx port) for QPs and TISes.
Allows to port remap QPs and TISes, overriding their
tx_affinity behavior.
- MODIFY_LAG
Remap QPs and TISes to another port.
- QUERY_LAG
Query whether LAG mode is active.
- DESTROY_LAG
HW exits LAG mode, returning to non-LAG behavior.
- CREATE_VPORT_LAG
Merge Ethernet flow steering, such that traffic received on port
two jumps to PF0 root flow table.
Available only in LAG mode.
- DESTROY_VPORT_LAG
Ethernet flow steering returns to non-LAG behavior.
Caps added:
- lag_master
Driver is in charge of managing the LAG.
This is currently the only option.
- num_lag_ports
LAG is supported only if this field's value is 2.
Other fields:
- QP/TIS tx port affinity
During LAG, this field controls on which port a QP or TIS resides.
- TIS strict tx affinity
When this field is set, the TIS will not be subject to port remap by
CREATE_LAG/MODIFY_LAG.
- LAG demux flow table
Flow table used for redirecting non user-space traffic back to
PF1 root flow table, if the packet was received on port two.

Now as all commands use mlx5 ifc interface, instead of doing two calls
for executing a command we embed command status checking into
mlx5_cmd_exec to simplify the interface.
Also we do here some cleanup for redundant software structures
(inbox/outbox) and functions and improved command failure output.

Prior to this patch we assumed that modify QP commands have the
same layout.
In ConnectX-4 for each QP transition there is a specific command
and their layout can vary.
e.g: 2err/2rst commands don't have QP context in their layout and before
this patch we posted the QP context in those commands.
Fortunately the FW only checks the suffix of the commands and executes
them, while ignoring all invalid data sent after the valid command
layout.
This patch removes mlx5_modify_qp_mbox_in and changes
mlx5_core_qp_modify to receive the required transition and QP context
with opt_param_mask if needed. This way the caller is not required to
provide the command inbox layout and it will be generated automatically.
mlx5_core_qp_modify will generate the command inbox/outbox layouts
according to the requested transition and will fill the requested
parameters.
