On recent Ideapad models the EC does not control the touchpad at all, so instead of sending KEY_TOUCHPAD_ON/ _OFF on touchpad toggle hotkey events, ideapad-laptop should send KEY_TOUCHPAD_TOGGLE and let userspace handle the toggling. Check for this by checking if the value read from VPCCMD_R_TOUCHPAD actually changes when receiving a touchpad-toggle hotkey event; and if it does not change send KEY_TOUCHPAD_TOGGLE to userspace to let userspace enable/disable the touchpad in software. Note this also drops the priv->features.touchpad_ctrl_via_ec check from ideapad_sync_touchpad_state() so that KEY_TOUCHPAD_TOGGLE will be send on laptops where this is not set too. This can be safely dropped now because the i8042_command(I8042_CMD_AUX_ENABLE/_DISABLE) call is now guarded by its own feature flag.
