The Toshiba Click Mini L9W keyboard dock has a single i2c-hid Elan device
for both the keyboard and the touchpad. Add support for the touchpad to
the hid-elan driver, rather then relying on mouse emulation.

Query the device's max_x and max_y value from the touchpad rather then
hardcoding it. This makes adding support for other USB ids a lot easier.

Elan has given me a (GPL-ed) Android driver for their non HID-mt touchpads
to help improve the upstream support.
Acoording to Elan what we are currently reporting as tool-width
really is a per-touch pressure. This always has a maximum of 255, so there
is no need to make the max configurable.

interfaces: keyboard, which exposes ordinary keys and second interface is
touchpad which also contains FlightMode button and audio mute led (which
