hcd_buffer_create - initialize buffer pools
int hcd_buffer_create (struct usb_hcd * hcd);
hcd the bus whose buffer pools are to be initialized
Call this as part of initializing a host controller that uses the dma
memory allocators. It initializes some pools of dma-coherent memory
that will be shared by all drivers using that controller, or returns a
negative errno value on error.
Call hcd_buffer_destroy to clean up after using those pools.
