Add mlx5_eq_{create/destroy}_generic APIs and EQE access methods, for
mlx5 core consumers generic EQs.
This API will be used in downstream patch to move page fault (RDMA ODP)
EQ logic into mlx5_ib rdma driver, hence it will use a generic EQ.
Current mlx5 EQ allocation scheme:
On load mlx5 allocates 4 (for async) + #cores (for data completions)
MSIX vectors, mlx5 core will assign 3 MSIX vectors for internal async
EQs and will use all of the #cores MSIX vectors for completion EQs,
(One vector is going to be reserved for a generic EQ).
After this patch an external user (e.g mlx5_ib) of mlx5_core
can use this new API to create new generic EQs with the reserved msix
vector index for that eq.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
