ARM: dts: meson: add USB support on Meson8 and Meson8b
This adds the DWC2 USB controller nodes and the corresponding USB2 PHY nodes to meson.dtsi (as the same - or at least a very similar) IP block is used on all SoCs (at the same physical address). Additionally meson8.dtsi and meson8b.dtsi add the required clocks to the DWC2 and USB2 PHY nodes, otherwise the DWC2 controller cannot be initialized by the dwc2 driver.
