[PATCH v2] dt-bindings: mfd: qcom,spmi-pmic: document rradc node

[Caleb Connolly]

Document the rradc node name, like adc-tm it's only used on a few
platforms, so differentiate it from the standard adc node.

V1: https://lore.kernel.org/linux-arm-msm/20221016175757.1911016-1-caleb.connolly@xxxxxxxxxx/
Changes since v1:
 * Add a new node instead of using the adc@ node
 * no longer depend on Luca's patch
