Move the regulator-ocp-notifier device node's regulator supply
properties out of kalama-pmic-overlay.dtsi and into the platform-
specific files: kalama-cdp.dtsi, kalama-mtp.dtsi, and kalama-qrd.dtsi.
This avoids problems when kalama-pmic-overlay.dtsi is included on
boards that do not have the full set of PMICs present. In that
case the regulator-ocp-notifier device may never be initialized
because some of the supplies that it depends on are not present.
