Changes in v3:
- Add patch with coding style changes to header
- Split patches: the use of the mask hw_engine initialization is one and the
  configfs handling is another
- Move the lookup table outside of the function looking up the mask:
  this will also be used in other patches in future
- Change the _show() method to pretty-print engine names: it's not the
  same format as passed in, but covers the "what was exactly parsed"
  while at the same time not require one to lookup the indexes in the
  source code (Stuart)
- Avoid the term "fuse off" (Matt Roper)
- Handle gcscs (Matt Roper)
- Improve and fold conditions for checking if the engine instance is out
  of bounds (Matt Roper)
- Link to v2: https://lore.kernel.org/r/20250520-engine-mask-v2-1-46e76f935b35@intel.com

Changes in v2:
- Fix build with CONFIG_CONFIGFS_FS=n
- Link to v1: https://lore.kernel.org/r/20250520-engine-mask-v1-1-ce6daf16d23b@intel.com
