drivers/usb/gadget/amd5536udc.c: avoid calling dma_pool_create() with NULL dev

Calling dma_pool_create() with dev==NULL will oops on a NUMA machine.
Rather than changing dma_pool_create() we wish to disallow passing
dev==NULL.  This requires fixing up the small number of drivers which are
passing in dev==NULL.

Use &dev->pdev->dev instead of NULL.
