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.
