            Fix SPDX license tag: 'LicenseRef-Callaway-BSD' -> 'BSD-2-Clause'

License analysis:
- Examined the License section in 'doc/cbios.txt' (the only license text
  shipped with the source; no separate COPYING or LICENSE file exists)
- Copyright holders: BouKiCHi (2002-2005), Reikan (2003),
  Maarten ter Huurne (2004-2010), Albert Beevendorp (2004-2011),
  Patrick van Arkel (2004-2005), Manuel Bilderbeek (2004,2010-2011),
  Joost Yervante Damad (2004-2006), Jussi Pitkanen (2004-2006),
  Eric Boon (2004-2007)
- The license text contains only two numbered clauses:
  1. "Redistributions of source code must retain the above copyright
     notice, this list of conditions and the following disclaimer."
  2. "Redistributions in binary form must reproduce the above copyright
     notice, this list of conditions and the following disclaimer in the
     documentation and/or other materials provided with the distribution."
- There is NO third "no-endorsement" clause
- Only two clauses means this is BSD-2-Clause, not BSD-3-Clause

Exhaustive audit:
- Total files in source tree: 107
- Source files with license headers (.asm): 40 of 43 (3 without headers
  are data-only or utility files: 'locale.asm', 'slot.asm',
  'tniasm-compat.asm')
- ALL 40 source file headers contain the identical BSD-2-Clause text
- No bundled libraries with separate licenses
- No license conflicts found

The correct SPDX identifier is 'BSD-2-Clause'.
