Document that references to data nodes shall use string-only references
instead of a device reference and a succession of the first package
entries of hierarchical data node references.

Update references for the ACPI _DSD documentation. In particular:
- Substitute _DSD property and hierarchical data extension documents with
the newer DSD guide that replaces both, and use its HTML form.
- Refer to the latest ACPI spec.
- Add data node reference documentation reference to graph documentation.

The data node reference documentation was missing a package that must
contain the property values, instead property name and multiple values
being present in a single package. This is not aligned with the _DSD
spec.
Fix it by adding the package for the values.
Also add the missing "reg" properties to two numbered nodes.

The :doc:`foo` tag is auto-generated via automarkup.py.
So, use the filename at the sources, instead of :doc:`foo`.

Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

In ACPI it is possible to make references to device objects only,
not to other objects inside a device.
In practice this means that hierarchical data extension targets
must be in parentheses to make them strings, or an ACPICA warning
will be produced.
