platform/x86: ideapad-laptop: Send KEY_TOUCHPAD_TOGGLE on some models
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.
