USB: EHCI: make ehci-vt8500 a separate driver
With the multiplatform changes in arm-soc tree, it becomes possible to enable the vt8500 platform at the same time as other platforms that require a conflicting EHCI bus glue. At the moment, this results in a warning like drivers/usb/host/ehci-hcd.c:1277:0: warning: "PLATFORM_DRIVER" redefined [enabled by default] drivers/usb/host/ehci-hcd.c:1257:0: note: this is the location of the previous definition drivers/usb/host/ehci-omap.c:319:31: warning: 'ehci_hcd_omap_driver' defined but not used [-Wunused-variable] and an ehci driver that only works on one of them. With the infrastructure added by Alan Stern in patch 3e0232039 "USB: EHCI: prepare to make ehci-hcd a library module", we can avoid this problem by turning a bus glue into a separate module, as we do here for the vt8500 bus glue.
