  Improve power consumption on Framework systems

Status in OEM Priority Project:
Status in systemd package in Ubuntu:
  In Progress

Bug description:
  [ Impact ]

   * Framework systems that have DP or HDMI cards connected will have
  increased power consumption even when nothing is connected to DP or
  HDMI ports since the cards don't default to autosuspend.

   * Backporting upstream patch that adds rules in
  hwdb.d/60-autosuspend.hwdb for Framework's HDMI and DP extensions.

  [ Test Plan ]

   * DUT: Framework with DP and HDMI:

  $ lsusb | grep Framework
  Bus 007 Device 002: ID 32ac:0003 Framework DisplayPort Expansion Card
  Bus 001 Device 002: ID 32ac:0002 Framework HDMI Expansion Card

   1. Autosuspend is not enabled before patch. Set to "on" in

  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-1/manufacturer
  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-1/power/control

  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-2/manufacturer
  $ cat /sys/devices/pci0000:00/0000:00:08.1/0000:c1:00.3/usb1/1-2/power/control

   2. Install patch
   3. Autosuspend is enabled for both extensions. Set to "auto" in power/control

  $ cat power/control

  [ Where problems could occur ]

   * During testing verified that both DP+HDMI display show good output after 
hot-plug, system suspend, and reboot. There might be some differences when 
hibernate and hotplug.
