Rafal Jaworowski 35d01728c6 Fix USB cache sync operations for platforms with non-coherent DMA. 
- usb_pc_cpu_invalidate() is called between [consecutive] reads from a device,
  so a sequence of BUS_DMASYNC_POSTREAD and _PREREAD should be used. Note we
  cannot use or'ed shorthand ( _POSTREAD | _PREREAD) for BUS_DMASYNC flags, as
  the low level bus dma sync operation is implementation dependent and we
  cannot assume the required order of operations to be guaranteed.

- usb_pc_cpu_flush() is called before writing to a device, so
  BUS_DMASYNC_PREWRITE should be used.
