msm8953-common: Add fingerprint navigation support

* Imported from berkeley-dev's kirin970-common tree, and edited.

* Opt to not use Moto's OneNav solution and instead just listen
  for keycodes without a middleman listener.

* This likely means we can't support the on-button-release
  events they do (keycode 615 for example).

* Add Needed sepolicy
