  QCA Rome bluetooth can not wakeup after USB runtime suspended.

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  == SRU Justification ==
  [Impact]
  Some QCA ROME bluetooth devices does not work after runtime suspended.

  [Fix]
  Latest mainline does not have this issue. The bisected commit is 
a0085f2510e8976614ad8f766b209448b385492f "Bluetooth: btusb: driver to enable 
the usb-wakeup feature".
  With this commit, the BT device now can wake host controller up.

  [Test]
  Cherry-picked the commit into Artful/OEM kernel and the issue is fixed.

  [Regression Potential]
  Low. usb-wakeup support shouldn't affect the driver's function.
