[PATCH 13/16] dt-bindings: arm: stm32mp2: allow child nodes since simple-mfd transition

[Fabrice Gasnier]

Adapt stm32-syscon on stm32mp2, since transition to simple-mfd, to support
usb2phy child nodes, that has a unit address.
This is a temporary update, as it depends on Marek's series [1]. This
should be dropped in later series revision.
It's a precursor to validate further DT addition on USB and Type-C.
