Title:
  Add missing ARM-cores to support Grace-based systems

Status in util-linux package in Ubuntu:
  New
Status in util-linux source package in Jammy:
  In Progress
Status in util-linux source package in Lunar:
  In Progress

Bug description:
  [Impact]
  When running "lscpu" on a Grace-based system + Ubuntu 22.04, it doesn't report a model name:

  Vendor ID: ARM
  Model: 0

  [Fix]
  Adding the additional arm_part to sys-utils/lscpu-arm.c solves the problem. The commit below adds the specific codes missing from Jammy's version.

  https://github.com/util-linux/util-
  linux/commit/6857cccbb4157d5da34ca98f77a0ac9d68e1e740

  [Evidence]
  When upstream code is compiled, output of lscpu is correctly displayed:
  Vendor ID: ARM
  Model name: Neoverse-V2

  [What Could Go Wrong]
  The fix does not apply directly to Jammy's version, as other commits change sys-utils/lscpu-arm.c. The suggestion is only to add the missing arm_part to the list.
