Add initial driver for ACPI NFIT-enumerated NVDIMMs. Driver enumerates NVDIMMs. Besides, for each found System Physical Address (SPA) range, spaN geom provider is created, which allows formatting and mounting the region as the normal volume. Also, /dev/nvdimm_spaN node is created, which can be read/written/mapped by userspace, the mapping is zero-copy. No support for block access methods implemented, labels are not parsed. No management interfaces are provided. Tested by: Intel, NetApp Sponsored by: The FreeBSD Foundation Approved by: re (gjb) MFC after: 2 weeks 2018-10-16 20:12:35 +00:00			`# $FreeBSD$`

nvdimm: only enumerate present nvdimm devices Not all child devices of the NVDIMM root device represent DIMM devices which are present in the system. The spec says (ACPI 6.2, sec 9.20.2): For each NVDIMM present or intended to be supported by platform, platform firmware also exposes an NVDIMM device ... under the NVDIMM root device. Present NVDIMM devices are found by walking all of the NFIT table's SPA ranges, then walking the NVDIMM regions mentioned by those SPA ranges. A set of NFIT walking helper functions are introduced to avoid the need to splat the enumeration logic across several disparate callbacks.
