Document compatible string for Exynos7870 DWC3-compatible USB 2.0 driver. The devicetree node requires three clocks, named "usbdrd20", "usbdrd20_ctrl_clk", and "usbdrd20_ref_clk". Unlike other variants, Exynos7870's USB node doesn't require extra regulators. Assert that the regulator nodes are required for all variants other than Exynos7870's on an individual basis, instead of asserting it globally.
