Since commit 93512dad33 ("dt-bindings: Improve validation build error
handling"), 'make dtbs_check' does not validate the schema fully.
If you want to check everything, you need to run two commands separately.
$ make ARCH=arm dt_binding_check
$ make ARCH=arm dtbs_check
They are exclusive each other, so you cannot do like this:
$ make ARCH=arm dt_binding_check dtbs_check
In this case, dt-doc-validate and dt-extract-example are skipped
because CHECK_DTBS is set.
Let's make it possible to run these two targets in a single command.
It will be useful for schema writers.

Schema errors can cause make to exit before useful information is
printed. This leaves developers wondering what's wrong. It can be
overcome passing '-k' to make, but that's not an obvious solution.
There's 2 scenarios where this happens.
When using DT_SCHEMA_FILES to validate with a single schema, any error
in the schema results in processed-schema.yaml being empty causing a
make error. The result is the specific errors in the schema are never
shown because processed-schema.yaml is the first target built. Simply
making processed-schema.yaml last in extra-y ensures the full schema
validation with detailed error messages happen first.
The 2nd problem is while schema errors are ignored for
processed-schema.yaml, full validation of the schema still runs in
parallel and any schema validation errors will still stop the build when
running validation of dts files. The fix is to not add the schema
examples to extra-y in this case. This means 'dtbs_check' is no longer a
superset of 'dt_binding_check'. Update the documentation to make this
clear.

Users without an existing python install may not have their PATH setup
for pip installed python programs already. Add a note about having the
DT validation programs in the PATH.

It wasn't obvious that this was a command to run based on 'make help',
so add it to the top-level help for devicetree builds. Also, add an
example to the documentation to show that db_binding_check can be run
with DT_SCHEMA_FILES= to only check one schema file instead of all of
them.
