Added a function to set PKEY index to IPoIB device driver using the
already present set_id function. PKEY index is attached to the QP
during state modification.

Previous support allowed connecting only a single QPN to the FT.
Now using a linked list multiple QPNs can be attached to the same FT.
Supporting attaching multiple underlay QPs is required for PKEY
support in which child and parent share the same FT.
The actual attaching/detaching FW commands will be called inside the
function symmetrically.
This change requires a change in IPoIB open and close functions, the
attaching/detaching to/from the FT is done each time we open/close.

During the creation of the underlay QP the PKEY index is unknown, the
PKEY index is known only when calling ndo_open.
PKEY index attached to the QP during state modification.
Splitting the functions will also make the code symmetric and more
readable. This split is also required for later PKEY support to be
called with the PKEY index during ndo_open.

PTP code is moved to core section of mlx5 driver in order to share
it between ethernet and infiniband. This movement involves the following
changes:
- Change mlx5e_ prefix to be mlx5_
- Add clock structs to Core
- Add clock object to mlx5_core_dev
- Call Init/Uninit clock from core init/cleanup
- Rename mlx5e_tstamp to be mlx5_clock

When cleaning rdma netdevice we need to save the mdev pointer
because priv is released when we release netdev.
This bug was found using the kernel address sanitizer (KASAN).

On interface remove, the clean-up was done incorrectly causing
an error in the log:
"SET_FLOW_TABLE_ROOT(0x92f) op_mod(0x0) failed...syndrome (0x7e9f14)"
This was caused by the following flow:
-ndo_uninit:
Move QP state to RST (this disconnects the QP from FT),
the QP cannot be attached to any FT unless it is in RTS.
-mlx5_rdma_netdev_free:
cleanup_rx: Destroy FT
cleanup_tx: Destroy QP and remove QPN from FT
This caused a problem when destroying current FT we tried to
re-attach the QP to the next FT which is not needed.
The correct flow is:
-mlx5_rdma_netdev_free:
cleanup_rx: remove QPN from FT & Destroy FT
cleanup_tx: Destroy QP
Fixes: 508541146af1 ("net/mlx5: Use underlay QPN from the root name space")

Add the ndo that supports change mtu for IPoIB.
The callback called from the ipoib ULP driver, that gives the ability to
change the SW and HW resources accordingly in the lower driver.

The mtu extra space that kept for the HW is specific for each link type,
and it is different in mlx5e and mlx5i modules.
Now it is kept in the priv structures, set by the mlx5e/mlx5i driver
accordingly.

Updating the carrier involves specific HW setting, each profile should
use its own function for that.
Both IPoIB and VF representor don't need carrier update function, since
VF representor has only a logical link to VF and IPoIB manages its own
link via ib_core upper layer.
