Previous revert of GRUB2 change that introduced usage of the generic EFI loader for all x86 boards in #3324 caused regressions, the one confirmed is #3348. This commit adds a specific patch that identifies the broken platforms based on SMBIOS data gathered in #3305 and falls back to the legacy loader there. Tested on Intel D525MW (falls back) and QEMU (no fallback).
Having smbios command in GRUB can help in future debugging, e.g. to add more CPUs that should use the linux loader fallback.
