Temporary add them as fixed regulators, waiting for full SCMI regulators support. This is a precursor patch to enable USB support on STM32MP13: - VDD_USB supplies the STM32MP13 USB internals - 3V3_SW supplies various peripherals, including the onboard HUB. Note: USB support requires these regulators to be enabled before entering the kernel.
