Subject: Documentation: ACPI: Fix data node reference documentation
From: Sakari Ailus <sakari.ailus@xxxxxxxxxxxxxxx>
commit a11174952205d082f1658fab4314f0caf706e0a8 upstream.
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.
