HID: elo: add quirks for broken firmware
One firmare version in the devices the driver takes care of is completely broken and needs periodic pokes from our side. We implemented this as a periodic delayed queue. The idea of the pokes was taken from the suse enterprise kernel, in particular from Libor's "Elo touchscreen firmware M workaround". I am quoting him here: This patch adds periodic polling of the Elo USB touchscreens. Needed as a workaround for devices with M-level firmware, otherwise these devices are known to misbehave (as reported by Elo developers).
