Bug description:
  [SRU Justification]

  [Impact]

  WiFi interfaces unsolicitedly down at resuming from s2idle.

  [Fix]

  Intel confirmed there is no CSME for WLAN POR for Linux. CSME for WLAN
  POR is only for Windows project design. Please remove or disable
  CONFIG_IWLMEI from Linux.

  [Test Case]

  Make sure iwlmei.ko is not built.

  [Where problems could occur]

  iwlmei was not enabled before 5.17 and was turned on automatically since
  then. This restores the state and shall not have impact on existing
  devices.
