[PATCH 14/19] dt-bindings: arm/cpus: Add schemas for "enable-method" dependencies

[Rob Herring (Arm)]

Replace the prose for properties dependent on specific "enable-method"
values with schemas defining the same requirements.

Both "qcom,acc" and "qcom,saw" properties appear to be required for any
of the Qualcomm enable-method values, so the schema is a bit simpler
than what the text said. The references to arm/msm/qcom,saw2.txt and
arm/msm/qcom,kpss-acc.txt are out of date, so just drop them.
