X86MachineState from it, make the functions previously extracted from
pc.c to x86.c independent from PCMachineState, using X86MachineState

This is so I2C devices can be found in the ACPI namespace. Currently
that's only IPMI, but devices can be easily added now.
Adding the devices required some PCI information, and the bus itself
to be added to the PCMachineState structure.
Note that this only works on Q35, the ACPI for PIIX4 is not capable
of handling an SMBus device.

This will make unversioned CPU models behavior depend on the
machine type:
* "pc-*-4.0" and older will not report them as aliases.
This is done to keep compatibility with older QEMU versions
after management software starts translating aliases.
* "pc-*-4.1" will translate unversioned CPU models to -v1.
This is done to keep compatibility with existing management
software, that still relies on CPU model runnability promises.
* "none" will translate unversioned CPU models to their latest
version. This is planned become the default in future machine
types (probably in pc-*-4.3).

move the acpi_nvdimm_state to the generic machine struct
instead of duplicating the same code in several machines.
It is also renamed into nvdimms_state and becomes a pointer.
nvdimm and nvdimm-persistence become generic machine options.
They become guarded by a nvdimm_supported machine class member.
We also add a description for those options.
