Elliott Hughes 96c1db7b9d Remove the repetitive warnings from the uapi headers.
Having

  WARNING: DO NOT EDIT, AUTO-GENERATED CODE - SEE TOP FOR INSTRUCTIONS

every four lines made the headers harder to read, made the diffs much worse

Bug: N/A
Test: builds, manually inspected files look right

*** To edit the content of this header, modify the corresponding
