Not only Geyser 3 but also Geyser 1 need to be reset after they become
idle to stop them from needlessly waking up the kernel. Do idle reset
on all touchpads, regardless of their version - if we see 10 empty
packets the touchpad needs to be reset; good touchpads should not send
empty packets anyway.
