fix adf display devices on Spreadtrum devices for Android 10

Browse Source 
* Somehow, when running GSI 10, Spreadtrum's adf driver do not show up
  with the correct name in /dev. I am not sure how this happens, but it
  seemed that a few `mknod`s fixed the problem. This was tested on
  Xiaomi Qin 2 Pro.
