usb: gadget: don't fail when DMA isn't present
When CONFIG_HAS_DMA isn't enabled, the UDC core gets build errors:
drivers/built-in.o: In function `dma_set_coherent_mask':
include/linux/dma-mapping.h:93: undefined reference to `dma_supported'
include/linux/dma-mapping.h:93: undefined reference to `dma_supported'
drivers/built-in.o: In function `usb_gadget_unmap_request':
drivers/usb/gadget/udc-core.c:91: undefined reference to `dma_unmap_sg'
drivers/usb/gadget/udc-core.c:96: undefined reference to `dma_unmap_single'
drivers/built-in.o: In function `usb_gadget_map_request':
drivers/usb/gadget/udc-core.c:62: undefined reference to `dma_map_sg'
drivers/usb/gadget/udc-core.c:71: undefined reference to `dma_map_single'
drivers/usb/gadget/udc-core.c:74: undefined reference to `dma_mapping_error'
Prevent this by protecting the DMA API routines with preprocessor tests.
