USB: remove struct usb_operations
All of the currently-supported USB host controller drivers use the HCD bus-glue framework. As part of the program for flattening out the glue layer, this patch (as769) removes the usb_operations structure. All function calls now go directly to the HCD routines (slightly renamed to remain within the "usb_" namespace). The patch also removes usb_alloc_bus(), because it's not useful in the HCD framework and it wasn't referenced anywhere.
