Property fetching functions which return number of successfully fetched
properties should not state that out-values are only modified if 0 is
returned. Fix this. Also, "pointer to return value" is slightly suboptimal

arguments). Rather use "pointer to found values".

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.

Instead of grouping alphabetically by third-party vendor, leading to
one-element enums, start sorting by Mali model number, as done for
Utgard.

This already allows us to de-duplicate two "arm,mali-t760" sections and
will make it easier to add new vendor compatibles.
