Add a kludge to switch "HP EliteBook 9470m" touchpad to multitouch mode if that
particular model has been detected by controller's PnP Id

To check if the kludge is working just do multi-finger gesture like "2-finger
scroll" and look in to /var/log/messages, you'll see lines starting with
"smoother1".

Following is a sample of /var/log/messages contents after "two-finger scroll"
has been done:
