This set of patches adds support for USB on the Exynos7885 SoC.
The Exynos7885 has a DWC3 compatible USB controller and an Exynos USB
PHY that theoretically supports USB3 SuperSpeed, but is not implemented
in any known device. The vendor kernel also stubs out USB3 functions, so
we do not support it.
While at it, since we need some new clocks implemented, also fix some
issues with the existing clock driver/bindings.
p.s.: Not realizing the USB PLL has a MUX on it made me waste I don't
even want to know how much time on troubleshooting why it's not
working...
