Add support of dump callback for mlx5 FW reporter. Once we trigger FW dump, the FW will write the core dump to its raw data buffer. The tracer translates the raw data to traces and save it to a cyclic array. Once dump is done, the saved traces data is filled into the dump buffer. In case syndrome is not zero the health buffer content will be printed as well. FW dump example: $ devlink health dump show pci/0000:82:00.0 reporter fw dump fw traces: timestamp: 509006640427 lost: false event_id: 185 msg: dump general info GVMI=0x0000 timestamp: 509006645474 lost: false event_id: 185 msg: GVMI management info, gvmi_management context: timestamp: 509006654463 lost: false event_id: 185 msg: [000]: 00000000 00000000 00000000 00000000 timestamp: 509006656127 lost: false event_id: 185 msg: [010]: 00000000 00000000 00000000 00000000 timestamp: 509006656255 lost: false event_id: 185 msg: [020]: 00000000 00000000 00000000 00000000 timestamp: 509006656511 lost: false event_id: 185 msg: [030]: 00000000 00000000 00000000 00000000 timestamp: 509006656639 lost: false event_id: 185 msg: [040]: 00000000 00000000 00000000 00000000 timestamp: 509006656895 lost: false event_id: 185 msg: [050]: 00000000 00000000 00000000 00000000 timestamp: 509006657023 lost: false event_id: 185 msg: [060]: 00000000 00000000 00000000 00000000 timestamp: 509006657180 lost: false event_id: 185 msg: [070]: 00000000 00000000 00000000 00000000 timestamp: 509006659839 lost: false event_id: 185 msg: CMDIF dbase from IRON: active_dbase_slots = 0x00000000 timestamp: 509006667391 lost: false event_id: 185 msg: GVMI=0x0000 hw_toc context: timestamp: 509006667647 lost: false event_id: 185 msg: [000]: 00000000 00000000 00000000 fffff000 timestamp: 509006667775 lost: false event_id: 185 msg: [010]: 00000000 00000000 00000000 80d00000 ... ...

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.
