ARM: dts: stm32: add PWR fixed regulators on stm32mp131

Browse Source 
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.
