[PATCH v2 7/9] dt-bindings: arm: stm32: Switch st,stm32mp23/25-syscfg into simple-mfd

[Marek Vasut <marex@nabladev.com>]

The st,stm32mp23-syscfg and st,stm32mp25-syscfg can have subnodes, which
represent the USB 2.0 FEMTO-PHY. Turn the syscfg into "simple-mfd" so the
PHYs would get populated by the OS.
