The current EDT graph logic only use properties directly under a
specific node to add dependencies. For nodes properties in
child-bindings, this means that the child phandles are only linked by
the child node itself, which does have an ordinal but no corresponding
"sturct device" in the code, causing those dependencies to be silently
ignored by gen_handles.py.
Fix that by adding the recursive logic to visit child bindings when
present, which causes all child node property handles to be linked to
the parent node.

Converting this to a dataclass will make it easier to type annotate.
Adding type annotations is incremental progress towards type checking
the entire module.

Just like we did for dtlib in 15e3e317f7
("dtlib: implement copy.deepcopy() for DT"), except this time it's for
EDT. This also can do no harm and will be useful for implementing
system devicetree support.
No functional changes expected under the assumption that no users are
relying on us having stashed the exact bindings_dirs list passed to
the constructor. This patch switches to making a defensive copy, which
is safer and makes implementing this a little cleaner.

Add test coverage for the child-binding include feature. It includes
verification of included properties as well as usage of allow/blocklist.

Regular dicts are insertion-ordered since CPython 3.6 and Python 3.7.
Zephyr now requires Python 3.8, so it should be OK to replace
OrderedDict with regular dict now. This results in less typing and
more readable object representations.
A nitpicker could argue that this is a functional change, since if a
user is doing 'assert isinstance(node.props, OrderedDict)', that will
fail now, but:
1. nobody is doing something like that in the zephyr tree
2. that would be a silly thing to do
3. we don't currently make any API stability guarantees
for this module right now anyway
so it should be fine.

For a single bus that supports multiple protocols, e.g. I3C and I2C,
the single value "bus:" setting is no longer sufficient, as a I3C bus
cannot be matched to a device having "on-bus: I2C". This commit
extends the "bus:" setting so that it can accept a list of values.
This change allows corresponding devicetree macros to be generated
so that DT_ON_BUS() can work properly in this scenario.

It can be useful to know what the index of a particular child is in
the list of nodes. Add a a helper for computing that and some test
cases.

This adds some tests in test_edtlib.py and test.dts to check all
common possible combination of ranges property usage and handling
by edtlib.

Currently all the *-names and *-cells properties are derived from the
name of the base <name>s property. This is a limitation because:
- It forces the base property name to be plural ending in -s
- It doesn't allow the english exception of plural words ending in -es
With this patch we add one additional property 'specifier-space' that
can be used to explicitly specify the base property name.

Add the ability to filter which properties get imported when we do an
include. We add a new YAML form for this:
include:
- name: other.yaml
property-blocklist:
- prop-to-block
or
include:
- name: other.yaml
property-allowlist:
- prop-to-allow
These lists can intermix simple file names with maps, like:
include:
- foo.yaml
- name: bar.yaml
property-allowlist:
- prop-to-allow
And you can filter from child bindings like this:
include:
- name: bar.yaml
child-binding:
property-allowlist:
- child-prop-to-allow

We are now in the process of extracting edtlib and dtlib into a
standalone source code library that we intend to share with other
projects.
Links related to the work making this standalone:
https://pypi.org/project/devicetree/https://python-devicetree.readthedocs.io/en/latest/https://github.com/zephyrproject-rtos/python-devicetree
This standalone repo includes the same features as what we have in
Zephyr, but in its own 'devicetree' python package with PyPI
integration, etc.
To avoid making this a hard fork, move the code that's being made
standalone around in Zephyr into a new scripts/dts/python-devicetree
subdirectory, and handle the package and sys.path changes in the
various places in the tree that use it.
From now on, it will be possible to update the standalone repository
by just recursively copying scripts/dts/python-devicetree's contents
into it and committing the results.
This is an interim step; do NOT 'pip install devicetree' yet.
The code in the zephyr repository is still the canonical location.
(In the long term, people will get the devicetree package from PyPI
just like they do the 'yaml' package today, but that won't happen for
the foreseeable future.)
This commit is purely intended to avoid a hard fork for the standalone
code, and no functional changes besides the package structure and
location of the code itself are expected.
