[PATCH 3/7] Documentation: ACPI: Fix data node reference documentation

[Sakari Ailus <sakari.ailus@linux.intel.com>]

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.

Fixes: b10134a3643d ("ACPI: property: Document hierarchical data extension references")
