ARM: dts: stm32: STM32MP13x SoC exposes SCMI regulators
Updates STM32MP13x SoC DTSI file to define the SoC voltage regulators
exposed by OP-TEE SCMI service and remove the fixed regulator
abstraction previously used until OP-TEE OS firmware embeds the
service which it does since its release tag 3.22.0.
