bnxt_en: Add support for devlink info command

Display the following information via devlink info command:
  - Driver name
  - Board id
  - Broad revision
  - Board Serial number
  - Board FW version
  - FW parameter set version
  - FW App version
  - FW management version
  - FW RoCE version

  Standard output example:
  $ devlink dev info pci/0000:3b:00.0
  pci/0000:3b:00.0:
  driver bnxt_en
  serial_number 00-10-18-FF-FE-AD-05-00
  versions:
      fixed:
        asic.id D802
        asic.rev 1
      running:
        fw 216.1.124.0
        fw.psid 0.0.0
        fw.app 216.1.122.0
        fw.mgmt 864.0.32.0
        fw.roce 216.1.15.0

[ This version has incorporated changes suggested by Jakub Kicinski to
  use generic devlink version tags. ]

v2: Use fw.psid
