nvdimm(4): Export NVDIMM health flags via sysctl
The ACPI NFIT specification defines a set of "NVDIMM State Flags". These flags are already reported by `acpidump -t', but this change makes them available on a per-device basis, in a format that is more easily parsed. To simplify this, introduce acpi_nfit_get_memory_maps_by_dimm(), which locates the (ACPI_NFIT_MEMORY_MAP)s associated with a given (nfit_handle_t).
