    acpi/cstate: Rework preamble operation for entering C-state
    
    - Save preamble operation in C-state struct, instead of choosing
      preamble operation at run time
    - Add machine depend C-state setup code to optimize out certain
      preamble operation for various CPU vendors
    - Fix up generic preamble operation setup according to ACPI spec
