The Exynos2200 SoC uses Synopsis eUSB2 PHY for USB 2.0. Add a new driver for it. eUSB2 on Exynos SoCs is usually paired alongside a USB PHY controller. Currently the driver is modelled to take and enable/disable the usb phy controller when needed. The driver is based on information from downstream drivers.
