ARM: dts: stm32: add PWR fixed regulators on stm32mp131
Add 1v1, 1v8 and 3v3 PWR regulators on stm32mp131. Temporary add them
as fixed regulators, waiting for full SCMI regulators support.
This is a precursor patch to enable USB support on STM32MP13.
Note: USB support requires these regulators to be enabled before
entering kernel.
