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.
