usb: quirks: Add no-lpm quirk for Acer C120 LED Projector
[ Upstream commit 32cb0b37098f4beeff5ad9e325f11b42a6ede56c ]
The Acer C120 LED Projector is a USB-3 connected pico projector which
takes both its power and video data from USB-3.
In combination with some hubs this device does not play well with
lpm, so disable lpm for it.
