Fixes stm32mp15*-scmi DTS files introduced in [1] to also access PWR regulators through SCMI service. This is needed since enabling secure only access to RCC clock and reset controllers also enables secure access only on PWR voltage regulators reg11, reg18 and usb33 hence these must also be accessed through SCMI Voltage Domain protocol. This change applies on commit [2] that already corrects issues from commit [1].
