This patchset adds the new PWR regulators compatible for STM32MP13:
"st,stm32mp13-pwr-reg".

As this node is just introduced by [1] and it is is not used by any
board in Linux, it is the good time to introduced this compatible
and update the STM32MP13 SoC dtsi without ABI break.

A new compatible is needed as the content of the PWR_CR3 register,
used by this driver change with new bits on STM32MP13 for SD IO domain:
- bit 23: VDDSD2VALID
- bit 22: VDDSD1VALID
- bit 16: VDDSD2RDY
- bit 15: VDDSD2EN
- bit 14: VDDSD1RDY
- bit 13: VDDSD1EN

I will push a update on STM32MP13 SoC dtsi if this new compatible
is accepted to preserve the bisectability.
