nvdimm: Simple namespace support
Add support for simple NVDIMM v1.2 namespaces from the UEFI
version 2.7 specification. The combination of NVDIMM regions and
labels can lead to a wide variety of namespace layouts. Here we
support a simple subset of namespaces where each NVDIMM SPA range
is composed of a single region per member dimm.

When attaching to NVDIMM devices, read and verify the namespace

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.

nvdimm: initialize SPA uuids statically.
The SPA ids are published numbers, so it's safe (if not a bit
annoying) to copy them into a source file.
