We add xhci node as child of dwc3 node in order to get data from device tree. It populates "xhci" child by name during initialization of host. This patch only effects if dwc3 node has a child named "xhci" not to disturb original path. We add "samsung,exynos-xhci" compatible in xhci platform driver to support Exynos SOCs. We introduce roothub wakeup, which uses roothub as system wakeup source. It needs xhci platform driver to override roothub ops.
