Provide a helper to extract the devicetree node_id for a GPIO
controller from a gpio phandle array. This can be used with
DEVICE_DT_GET() to directly reference the corresponding controller
device.

Rework some section titles and separate the API into its own sub-page
in the reference section.
This is prep work for adding generated reference material on
devicetree bindings.

Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

The documentation was not updated following a change to the way
DT_PROP_LEN works which was made in review. Fix it.

This is joint work with Kumar Gala (see signed-off-by).
Document the changes to the generated node macros in macros.bnf,
moving the old file to legacy-macros.bnf and putting it in its own
section.
The actual generated macros are now a low-level detail, so rewrite the
foregoing sections as examples in terms of the new <devicetree.h> APIs.
