This includes:
* support allocation of CQ with the TIMESTAMP_COMPLETION creation flag.
* add timestamp_mask and hca_core_clock to query_device, reporting the
number of supported timestamp bits (mask) and the hca_core_clock frequency.
* return hca core clock's offset in query_device vendor's data,
this is needed in order to read the HCA's core clock.

In order to read the HCA's cycle counter efficiently in
user space, we need to map the HCA's register.
This is done through mmap call.

In order to expose timestamp we need to expose two new attributes in
query_device to be used for CQ completion time-stamping:
timestamp_mask - how many bits are valid in the timestamp, where timestamp
values could be 64bits the most.
hca_core_clock - timestamp is given in HW cycles, the frequency in KHZ units
of the HCA, necessary in order to convert cycles to seconds.
This is added both to ib_query_device and its respective uverbs counterpart.

Currently, ib_create_cq uses cqe and comp_vecotr instead
of the extendible ib_cq_init_attr struct.
Earlier patches already changed the vendors to work with
ib_cq_init_attr. This patch changes the consumers too.

(completion vector) in addition to a new flags field.
All vendors' create_cq callbacks are changed in order

A reorganisation of the PD allocation and deallocation in commit
9ba1377daa ("RDMA/ocrdma: Move PD resource management to driver.")
introduced a double free on pd, as detected by static analysis by
smatch:
drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:682 ocrdma_alloc_pd()
error: double free of 'pd'^
The original call to ocrdma_mbx_dealloc_pd() (which does not kfree
pd) was replaced with a call to _ocrdma_dealloc_pd() (which does
kfree pd). The kfree following this call causes the double free,
so just remove it to fix the problem.

This code causes a static checker warning:
drivers/infiniband/hw/usnic/usnic_uiom.c:476 usnic_uiom_alloc_pd()
warn: passing zero to 'PTR_ERR'
This code isn't buggy, but iommu_domain_alloc() doesn't return an error
pointer so we can simplify the error handling and silence the static
checker warning.
The static checker warning is to catch place which do:
if (!ptr)
return ERR_PTR(ptr);

Registering an event handler is done for a device. This device may have
one RoCE port (no SA cap) and one InfiniBand port (has SA cap).
Therefore, warning from the event handler about a specific port that
doesn't have SA cap is correct but pollutes the kernel log without a
need.

The unwinding clean up code are err_create_flow starts at the current
index i. That means we shouldn't increment i until we're really sure
we won't have to destroy the current flow; otherwise we might
increment the index, fail inside an is_bonded block, and end up
accessing off the end of the reg_id[] array.

As of commit 5eb620c81ce3 "IB/core: Add helpers for uncached GID and P_Key
searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in
the ib_device.
The per port core capability flags to be added later are also immutable data to
be stored in the ib_device object.
In preparation for this create a structure for per port immutable data and
place the pkey and gid table lengths within this structure.
"get_port_immutable" is added as a mandatory device function to allow the
drivers to fill in this data.

The addition of the rdma_cap_ib_mad is technically broken in ib_umad_remove_one
because the loop "i" value is not a port value.
This bug resulted in the ib_umad failing to properly remove its resources when
the core capability functions were converted to bit fields.
NOTE: e17371d73908 did not result in broken behavior on its own. It was only
an issue when the implementation of rdma_cap_ib_mad was changed.
Pass the port value to rdma_cap_ib_mad.
