qlnxr: cleanup secondary effects from EOL purge

DEFINE_ALLOC_MR became unconditionally true, but it isn't used anywhere
now. Several places depended upon DEFINE_IB_FAST_REG, but that is now
always false.
Similarly DEFINE_IB_UMEM_WITH_CHUNK became always false/undefined.
DEFINE_IB_AH_ATTR_WITH_DMAC is now unconditionally true.

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):

ibcore: Declare ib_post_send() and ib_post_recv() arguments const

Since neither ib_post_send() nor ib_post_recv() modify the data structure
their second argument points at, declare that argument const. This change
makes it necessary to declare the 'bad_wr' argument const too and also to
modify all ULPs that call ib_post_send(), ib_post_recv() or
ib_post_srq_recv(). This patch does not change any functionality but makes
it possible for the compiler to verify whether the
ib_post_(send|recv|srq_recv) really do not modify the posted work request.
