Revert "hid-multitouch: Filter collections by application usage."

This reverts commit 0840b80c.

This patch is already upstreamed in v4.4, commit
658d4aed (HID: hid-multitouch: Filter collections by application usage.),
and further fixed/cleaned up afterwards in commits
c2ef8f21 (HID: multitouch: add support for trackpads),
76f5902a (HID: hid-multitouch: Simplify setup and frame synchronization) et al.

By having this duplicate patch in AOSP we are doing redundant
checks for Touchscreen and Touchpad devices.
