  x86/CPU/AMD: Terminate the erratum_1386_microcode array (2024-11-26 15:12:00 +0100)

----------------------------------------------------------------
- Add a terminating zero end-element to the array describing AMD CPUs affected
  by erratum 1386 so that the matching loop actually terminates instead of
  going off into the weeds

- Update the boot protocol documentation to mention the fact that the
  preferred address to load the kernel to is considered in the relocatable
  kernel case too

- Flush the memory buffer containing the microcode patch after applying
  microcode on AMD Zen1 and Zen2, to avoid unnecessary slowdowns

- Make sure the PPIN CPU feature flag is cleared on all CPUs if PPIN has been
  disabled
