x86/cpu/cyrix: Remove {get,set}Cx86_old macros used for Cyrix processors

The getCx86_old() and setCx86_old() macros have been replaced with
correctly working getCx86() and setCx86(), so remove these unused macros.

  * NSC/Cyrix CPU indexed register access. Must be inlined instead of
  * macros to ensure correct access ordering
  * Access order is always 0x22 (=offset), 0x23 (=value)

- * When using the old macros a line like
- *   setCx86(CX86_CCR2, getCx86(CX86_CCR2) | 0x88);
