Documentation: ACPI: Fix data node reference 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.
Fixes: b10134a3643d ("ACPI: property: Document hierarchical data extension references")
