This patchset introduces the USB Host driver for i.MX28 CPU, utilising the
generic USB PHY infrastructure.
V2: Introduce stub imx-usb driver that then registers the PHY and EHCI drivers.
V3: Add the HCD on demand based on the PHY's state (only add HCD if it's host).
Currently, only the HOST mode is supported.
