Add a compatible for the exynos8890-dwusb3 node. It features the same
clocks and regulators as exynos7, so reuse its compatible.

Document compatible string for Exynos7870 DWC3-compatible USB 2.0
driver. The devicetree node requires three clocks, named "bus_early",
"ref", and "ctrl".
Unlike other variants, Exynos7870's USB controller requires a single
3.0V regulator. Assert that the other 1.0V regulator requirement is
enforced on variants individually other than Exynos7870's.

The Exynos5433 DTSI had always different order of DWC USB3 controller
clocks than the binding. The order in the binding was introduced in the
commit 949ea75b7b ("dt-bindings: usb: samsung,exynos-dwc3: convert to
dtschema") converting to DT schema. The Linux driver does not care
about order and was always getting clocks by name. Therefore assume the
DTS is the preferred order and correct the binding.

The Samsung Exynos SoC USB 3.0 DWC3 Controller is a simple wrapper of
actual DWC3 Controller device node. It handles necessary Samsung
Exynos-specific resources (regulators, clocks), but does not have its
own MMIO address space.
However neither simple-bus bindings nor dtc W=1 accept device nodes in
soc@ node which do not have unit address.
