Subject: Add downstream x86_64 versioned 'pc' & 'q35' machine types
Adding changes to add RHEL machine types for x86_64 architecture.
Signed-off-by: Miroslav Rezanina <mrezanin@redhat.com>
---
Rebase notes (9.1.0 rc0):
- Merged pc_q35_machine_rhel_options back into
pc_q35_machine_options to reduce delta to upstream
- Convert to new DEFINE_(I440FX|Q35)_MACHINE macros
Rebase notes (9.1.0 rc4):
- Moved x86 cpu deprecation note to device disable patch
Merged patches (9.1.0 rc0):
- 043ad5ce97 Add upstream compatibility bits (partial)
