HID: asus: Add support for multi-touch touchpad on Medion Akoya E1239T 

The multi-touch touchpad found on the Medion Akoya E1239T's keyboard-dock,
uses the same custom multi-touch protocol as the Asus keyboard-docks
(same chipset vendor, Integrated Technology Express / ITE).

Add support for this using the existing multi-touch touchpad support in
the hid-asus driver.
