Bug description:
  [Impact]
  USB reset-resume quirk prevents the device from runtime suspending,
  which increases power usage.

  [Test]
  With the patch, the power consumption decreases 0.5W.
  The tested machine doesn't need the quirk to make btusb work.

  [Fix]
  Update the btusb reset-resume quirk with a DMI based version, which can
  be more specific.

  [Regression Potential]
  Low.
  Everthing is in mainline, and I haven't seen any new report about this
  issue for some time.
