crypto: ccree - improve kerneldoc in cc_hw_queue_defs.h

Miscellaneous improvements:
  - Start comment blocks with "/**" to enable kerneldoc,
  - Fix descriptor type of set_dout_mlli(),
  - Fix copied config parameter of set_cipher_config1(),
  - Fix copied config parameter of set_bytes_swap(),
  - Add missing function names to kerneldoc headers,
  - Add missing parameter descriptions,
  - Remove descriptions for nonexistent parameters,
  - Add missing colons,
  - Remove references to obsolete camelcase parameter names,
  - Sort according to actual parameter order,
  - Fix grammar and spelling.
