HID: asus: Add support for T100 touchpad
Add support for the Asus T100 touchpad in multi-touch mode (rather
then mouse emulation mode). It turns out that the Asus T100 touchpad
is identical to the already supported i2c-hid Asus touchpads, so
adding support for it was easy.
The only significant difference is that the reported x-coordinates
range on the T100 touchpad is somewhat lower then the range on the
already supported touchpads.
