machine: Move nvdimms state into struct MachineState

Browse source 
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.
