[clang, hexagon] Update copyright, license text (#107161)
When this file was first contributed - `28b01c59c93d ([hexagon] Add
{hvx,}hexagon_{protos,circ_brev...}, 2021-06-30)` - I incorrectly
included a QuIC copyright statement with "All rights reserved". I should
have contributed this file with the `Apache+LLVM exception` license.diff --git a/clang/lib/Headers/hexagon_types.h b/clang/lib/Headers/hexagon_types.h
