The xHCI controller on various Intel SoCs has an extended cap mmio-range which contains registers to control the muxing to the xHCI (host mode) or the dwc3 (device mode) and vbus-detection for the otg usb-phy. Having a role-sw driver included in the xHCI code (under drivers/usb/host) is not desirable. So this commit adds a simple handler for this extended capability, which creates a platform device with the caps mmio region as resource, this allows us to write a separate platform role-sw driver for the role-switch. Note this commit adds a call to the new xhci_ext_cap_init() function to xhci_pci_probe(), it is added here because xhci_ext_cap_init() must be called only once. If in the future we also want to handle ext-caps on non pci xHCI HCDs from xhci_ext_cap_init() a call to it should also be added to other bus probe paths.
