Add devlink flash update command. Advanced NICs have firmware stored in flash and often cryptographically secured. Updating that flash is handled by management firmware. Ethtool has a flash update command which served us well, however, it has two shortcomings: - it takes rtnl_lock unnecessarily - really flash update has nothing to do with networking, so using a networking device as a handle is suboptimal, which leads us to the second one: - it requires a functioning netdev - in case device enters an error state and can't spawn a netdev (e.g. communication with the device fails) there is no netdev to use as a handle for flashing. Devlink already has the ability to report the firmware versions, now with the ability to update the firmware/flash we will be able to recover devices in bad state. To enable updates of sub-components of the FW allow passing component name. This name should correspond to one of the versions reported in devlink info. v1: - replace target id with component name (Jiri).

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.
