mlx5/mlx5en: Add SQ remap support

Add support to map an SQ to a specific schedule queue using a
special WQE as performance enhancement.

SQ remap operation is handled by a privileged internal queue, IQ,
and the mapping is enabled from one rate to another.

The transition from paced to non-paced should however always go
through FW.

ibcore: Kernel space update based on Linux 5.7-rc1.

Overview:

This is the first stage of a RDMA stack upgrade introducing kernel
changes only based on Linux 5.7-rc1.

This patch is based on about four main areas of work:
- Update of the IB uobjects system:
- The memory holding so-called AH, CQ, PD, SRQ and UCONTEXT objects
is now managed by ibcore. This also require some changes in the
kernel verbs API. The updated verbs changes are typically about
initialize and deinitialize objects, and remove allocation and
free of memory.

- Update of the uverbs IOCTL framework:
- The parsing and handling of user-space commands has been
completely refactored to integrate with the updated IB uobjects
system.

- Various changes and updates to the generic uverbs interfaces in
device drivers including the new uAPI surface.

- The mlx5_ib_devx.c in mlx5ib and related mlx5 core changes.

Dependencies:

- The mlx4ib driver code has been updated with the minimum changes
needed.

- The mlx5ib driver code has been updated with the minimum changes
needed including DV support.

Compatibility:

- All user-space facing APIs are backwards compatible after this
change.

- All kernel-space facing RDMA APIs are backwards compatible after
this change, with exception of ib_create_ah() and ib_destroy_ah()
which takes a new flag.

- The "ib_device_ops" structure exist, but only contains the driver ID
and some structure sizes.

Differences from Linux:

- Infiniband drivers must use the INIT_IB_DEVICE_OPS() macro to set
the sizes needed for allocating various IB objects, when adding
IB device instances.

Security:

- PRIV_NET_RAW is needed to use raw ethernet transmit features.
- PRIV_DRIVER is needed to use other privileged operations.

Based on upstream Linux, Torvalds (5.7-rc1):

Do not inline transmit headers and use HW VLAN tagging if supported by mlx5en(4).

Query the minimal inline mode supported by the card.
When creating a send queue, cache the queried mode and optimize the transmit
if no inlining is required. In this case, we can avoid touching the headers
cache line and avoid dirtying several more lines by copying headers into
the send WQEs. Also, if no inline headers are used, hardware assists in
the VLAN tag framing.
