dt-bindings: arm: qcom: add QAR2130P board

Add the Qualcomm QAR2130P development board using the Qualcomm AR2 Gen1
aka SAR2130P platform.

The qcom-soc.yaml chunks use explicit 'sa|sar' instead of just 'sar?' to
be more obvious for reviewers and to ease future extensions. Overuse of
the regular expressions can easily end up with the hard-to-read and
modify schema.
