Some SpacemiT K1 boards (like OrangePi R2S) provide USB VBUS
through a controllable regulator. Add support for the optional
vbus-supply property so the regulator can be properly managed
in host mode instead of left always-on. Note that this doesn't
apply to USB Hub downstream ports with different VBUS supplies.
The enabled and disabled actions of the regulator are handled
automatically by devm_regulator_get_enable_optional().

The EIC7700 instantiates two USB 3.0 DWC3 IPs, each of which is backward
compatible with USB interfaces. It supports Super-speed (5Gb/s), DRD mode,
and compatible with xHCI 1.1, etc. Each of instances supports 16 endpoints
in device's mode and max 64 devices in host's mode.
This module needs to interact with the NOC via the AXI master bus, thus
requiring some HSP configuration operations to achieve this. Ops include
bus filter, pm signal or status to usb bus and so on.

devm_clk_bulk_get_all_enabled() is used in the probe, so
clk_bulk_disable_unprepare() should not be called explicitly in the remove
function.

Add layerscape dwc3 support by using flatten dwc3 core library. Layerscape
dwc3 need set gsbuscfg0-reqinfo as 0x2222 when dma-coherence set.

Add software-managed properties for the flattened model, which does not
need to use device tree properties to pass down information to the
common DWC3 core.
Add 'properties' in dwc3_probe_data and set default values for existing
users (dwc3-qcom, dwc3-generic-plat).
No functional changes.
