The Kconfig settings for uhci-hcd are too permissive; they allow the driver to be built without any bus-glue modules configured (USB_UHCI_HCD enabled, PCI disabled, SPARC_LEON disabled, ARCH_VT8500 enabled, and USB_UHCI_PLATFORM disabled). This patch fixes the problem by rearranging the dependencies. Now the platform-dependent config options don't depend on USB_UHCI_HCD; instead it depends on them. Furthermore, there is no user-selectable choice as to which glue modules will be built. If USB_UHCI_HCD is enabled then all applicable bus glues will be built.
