As NVDIMM support is looming for ARM and SPAPR, let's
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.

v3 -> v4:
- s/object_class_property_*/object_property_*
v2 -> v3
- nvdimms_state becomes a pointer
- add machine class nvdimm_supported
v1 -> v2:
- s/acpi_nvdimm_state/nvdimms_state
- remove ms->nvdimms_state.is_enabled initialization to false.

It's a pity that we are moving away from class properties back to
instance properties here, but we have no code today that rely on
class properties only. For example, "-machine pc,help" still
shows the nvdimm properties with this patch.
