This is not a fallback compatible, it must be present in addition to
"qcom,pronto-v*". It is also not documented in qcom,wcnss-pil.txt.  This
is the reason for documenting it in a separate commit.

This compatible is used in the wcn36xx driver to determine which
register must be accessed. However it isn't immediately clear why the
wcn36xx driver relies on this extra compatible string rather than just
looking for "qcom,pronto-v*".

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.
