[PATCH v3 8/9] arm64: dts: st: Add USB nodes on stm32mp231

Add USB controller and PHY nodes to stm32mp231 DT.
This includes two USB 2.0 FEMTO PHYs, USB 2.0 host
controller and DWC3 DRD controller nodes.

V2: - Fix up Sob/Cdb lines
    - Move PHY into syscfg subnode
    - Turn st,stm32mp23-syscfg into simple-mfd
    - Use clock-cells = <1> to discern OSC and future PLL clock from the PHY
V3: - Drop combophy which is not present on MP23
    - Describe OHCI clock as the CMN clock
