Christoph Hellwig edfbcb321f usb: add a hcd_uses_dma helper ... The USB buffer allocation code is the only place in the usb core (and in fact the whole kernel) that uses is_device_dma_capable, while the URB mapping code uses the uses_dma flag in struct usb_bus. Switch the buffer allocation to use the uses_dma flag used by the rest of the USB code, and create a helper in hcd.h that checks this flag as well as the CONFIG_HAS_DMA to simplify the caller a bit.
