Edward Smyth 82bdf7c8c7 Code cleanup: Copyright notices 
- Standardize formatting (spacing etc).
- Add full copyright to cmake files (excluding .json)
- Correct copyright and disclaimer text for frame and
  zen, skx and a couple of other kernels to cover all
  contributors, as is commonly used in other files.
- Fixed some typos and missing lines in copyright
  statements.
