Commit 27e5dd13 fixed a bunch of uses of "device tree" in the
documentation, but accidentally hit the part of the documentation
that stated that "devicetree" should be preferred over "device tree".

There are two set of code supporting x86_64: x86_64 using x32 ABI,
and x86 long mode, and this consolidates both into one x86_64
architecture and SoC supporting truly 64-bit mode.
() Removes the x86_64:x32 architecture and SoC, and replaces
them with the existing x86 long mode arch and SoC.
() Replace qemu_x86_64 with qemu_x86_long as qemu_x86_64.
() Updates samples and tests to remove reference to
qemu_x86_long.
() Renames CONFIG_X86_LONGMODE to CONFIG_X86_64.

DTSpec writes this as a single word, presumably to make it easier to
grep for / more precise. Follow along in the rest of the docs now that
our main DT docs page agrees with this usage.

The K6X example is part of the wrong subsection (devicetree vs

Added in 2.0, along with some binding format simplifications in 2.1.
Bunch of other stuff that could be mentioned, but keep it relatively
short.

Instead of
properties:
compatible:
constraint: "foo"
, just have
compatible: "foo"
at the top level of the binding.
For backwards compatibility, the old 'properties: compatible: ...' form
is still accepted for now, and is treated the same as a single-element
'compatible:'.
The old syntax was inspired by dt-schema (though it isn't
dt-schema-compatible), which is in turn a thin wrapper around
json-schema (the idea is to transform .dts files into YAML and then
verify them).
Maybe the idea was to gradually switch the syntax over to dt-schema and
then be able to use unmodified dt-schema bindings, but dt-schema is
really a different kind of tool (a completely standalone linter), and
works very differently from our stuff (see schemas/dt-core.yaml in the
dt-schema repo to get an idea of just how differently).
Better to keep it simple.
This commit also piggybacks some clarifications to the binding template
re. '#cells:'.

- Explain what it means to enable nodes (and for a node to be disabled)
with some sample code from the .dts(i) files
- Explain the '&foo { ... }' syntax
- Linkify files with :zephyr_path:
- Simplify and shorten wording a bit

Add some information that would've saved me a lot of time:
- Give an overview of how device tree nodes and bindings fit together,
with examples. Assume people might be coming at it without knowing
anything about device tree.
- Explain how 'inherits' works in more detail
- Explain what 'parent/child: bus: ...' does more concretely, and what
problem it solves
- Add more examples to show what things look like in the .dts file
- Clean up the language a bit and make things more consistent
Also fix some errors, like 'properties: compatible: ...' being wrong
(missing 'constraint:' and compatible strings in the wrong place).

Linking to API material requires knowing the pecularities of how
doxygen, sphinx, and breathe work. In an attempt to hide some of this
we're preparing the current docs to allow use of configuration defaults
that will let us more simply use a default role that will hunt for a
reference target in the various domains that are available by using a
default "role" of "all". This will let us use the simple notation
`functionname` or `typename` without fully specifying the reference as
:c:func:`functionname`.
This patch cleans up exising docs that were (incorrectly) using single
backtics where double backtics should have been used, and also found
some typos (such as a space between the role name and the reference,
such as :file: `filename`, and a missing colon such as
c:func:`functionname`)
This is a start to address issue #14313

There is no symbol called CONFIG_SRAM. Mention CONFIG_SRAM_SIZE and
CONFIG_SRAM_BASE_ADDRESS instead, and also mention that the DT_* values
they're generated from.
This gets rid of a false-positive undefined Kconfig symbol reference
too.
