HID: Add quirk for Logitech Casa touchpad
[ Upstream commit dd2c345a94cfa3873cc20db87387ee509c345c1b ]
This device sometimes doesn't send touch release signals when moving
from >=4 fingers to <4 fingers. Using MT_QUIRK_NOT_SEEN_MEANS_UP instead
of MT_QUIRK_ALWAYS_VALID makes sure that no touches become stuck.
MT_QUIRK_FORCE_MULTI_INPUT is not necessary for this device, but does no
harm.
