Add support for the DWC3 USB controller found on Google Tensor G5 (codename: laguna). The controller features dual-role functionality and hibernation. The primary focus is implementing hibernation support in host mode, enabling the controller to enter a low-power state (D3). This is particularly relevant during system power state transition and runtime power management for power efficiency. Highlights: - Align suspend callback with dwc3_suspend_common() for deciding between a full teardown and hibernation in host mode. - Integration with `psw` (power switchable) and `top` power domains, managing their states and device links to support hibernation. - A notifier callback dwc3_google_usb_psw_pd_notifier() for `psw` power domain events to manage controller state transitions to/from D3. - Coordination of the `non_sticky` reset during power state transitions, asserting it on D3 entry and deasserting on D0 entry in hibernation scenario. - Handling of high-speed and super-speed PME interrupts that are generated by remote wakeup during hibernation.

# We want to keep this requirement in order to be able to compile
