i40e: Align devlink info versions with ice driver and add docs



Align devlink info versions with ice driver so change 'fw.mgmt'
version to be 2-digit version [major.minor], add 'fw.mgmt.build'
that reports mgmt firmware build number and use '"fw.psid.api'
for NVM format version instead of incorrect '"fw.psid'.
Additionally add missing i40e devlink documentation.

====================
i40e devlink support
====================

This document describes the devlink features implemented by the ``i40e``
device driver.

Info versions
=============

The ``i40e`` driver reports the following versions

.. list-table:: devlink info versions implemented
    :widths: 5 5 5 90

    * - Name
      - Type
      - Example
      - Description
    * - ``board.id``
      - fixed
      - K15190-000
      - The Product Board Assembly (PBA) identifier of the board.
    * - ``fw.mgmt``
      - running
      - 9.130
      - 2-digit version number of the management firmware that controls the
        PHY, link, etc.
    * - ``fw.mgmt.api``
      - running
      - 1.15
      - 2-digit version number of the API exported over the AdminQ by the
        management firmware. Used by the driver to identify what commands
        are supported.
    * - ``fw.mgmt.build``
      - running
      - 73618
      - Build number of the source for the management firmware.
    * - ``fw.undi``
      - running
      - 1.3429.0
      - Version of the Option ROM containing the UEFI driver. The version is
        reported in ``major.minor.patch`` format. The major version is
        incremented whenever a major breaking change occurs, or when the
        minor version would overflow. The minor version is incremented for
        non-breaking changes and reset to 1 when the major version is
        incremented. The patch version is normally 0 but is incremented when
        a fix is delivered as a patch against an older base Option ROM.
    * - ``fw.psid.api``
      - running
      - 9.30
      - Version defining the format of the flash contents.
    * - ``fw.bundle_id``
      - running
      - 0x8000e5f3
      - Unique identifier of the firmware image file that was loaded onto
        the device. Also referred to as the EETRACK identifier of the NVM.
