[PATCH v4 3/4] arm64: dts: st: Add USB nodes on stm32mp231

[Marek Vasut <marex@nabladev.com>]

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
V4: - Cover USB2PHY2 SYSCFG_USB2PHY2TRIM2CR in reg property
    - Undo simple-mfd conversion of syscfg node
    - Split this from series arm64: dts: phy: st: usb: Add STM32MP2 USB support
