Pronto-v3 is similar to pronto-v2. It requires two power domains, and it
requires the xo clock. It is used on the MSM8953 platform.

This is a direct conversion of the existing txt documentation to YAML.
It is in preparation for the addition of pronto-v3 to the docs. This
patch doesn't document any of the existing subnodes/properties that are
not documented in the existing txt file. That is done in a separate
patch.

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*".

The pronto v3 remoteproc is similar to pronto v2. It is found on the
MSM8953 platform, which is used by SDM450, SDM625, SDM626, APQ8053 and
other SoCs. Since the configuration is same on all SoCs, a single
compatible is used.
