Bug description:
  [ Impact ]

   * It prevents the users of Xilinx boards to use latest versions of
  Xilinx SDK tools.

   * Since Ubuntu is officially supports  Xilinx Kria boards, we need to
  add Xilinx OEM support into freeipmi to enable latest Xilinx SDK tools
  on jammy, kinetic and lunar.

  
  [ Test Plan ]

   * Xilinx OEM data parsing is not supported on current version of
  freeipmi. So when you try to run `sudo ipmi-fru --fru-file
  /sys/bus/i2c/devices/1-0050/eeprom --interpret-oem-data` on a Xilinx
  Kria board you wont be able to get the oem specific data.

   * When the patch is applied, you must be able to see the Xilinx OEM data parsed successfully as in following output.
  ```
  ubuntu at kria:~$ sudo ipmi-fru --fru-file /sys/bus/i2c/devices/1-0050/eeprom --interpret-oem-data

  [ Where problems could occur ]

   * Since the change is only on OEM data parsing part of `ipmi-fru`
  tool it could only break `--interpret-oem-data` option for Xilinx
  boards.

   * This change must not introduce a regression since the Xilinx OEM
  support will be newly added via this patch.

   * Plus, patch is already in stable branch of the upstream project so
  it is accepted by the maintainer as a stable patch.

  
  [ Other Info ]
   
   * This patch request is created after evaluating LP #2015825.
