The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad which is connected to an ITE 8595 USB keyboard controller chip. This keyboard has the same quirk for its rfkill / airplane mode hotkey as other keyboards with the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds this keyboards USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard.
