Add case for CT_CENTAURV4 with version 4.0.0 (0x4000) to support the new CPU revision.

Configuration values based on similar high-performance cores (case 0x3 3.x.x and case 0x2):

  • Add version range 0x4000~0x4fff for CentaurV4 in case 0x4
  • Configure MSMPR, MCCR2, MXSTATUS, MHINT, MHINT2, MHCR, MHINT4
  • Add MENVCFG configuration for 64-bit mode
