  x86/cpu/amd: Enable Zenbleed fix for AMD Custom APU 0405 (2023-08-11 22:52:29 +0200)

----------------------------------------------------------------
- Do not parse the confidential computing blob on non-AMD hardware as it
  leads to an EFI config table ending up unmapped

- Use the correct segment selector in the 32-bit version of getcpu() in
  the vDSO

- Make sure vDSO and VVAR regions are placed in the 47-bit VA range even
  on 5-level paging systems

- Add models 0x90-0x91 to the range of AMD Zenbleed-affected CPUs
