bindings: add support for qcom,ucsi-glink

The UCSI Glink device handles the communication between OPM on
the Application processor and PPM which is charger firmware
running on the remote subsystem (e.g. DSP) over PMIC Glink.

This is a snapshot taken as of qcom-6.1
commit de2a781818d7 ("bindings: add support for qcom,ucsi-glink")
which was then converted to yaml.
