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.
