[PATCH] more dma fixes

[Sascha Hauer]

Hi All,

Based on Marcs series here are some more fixes to the cache handling for
USB/ehci. As Marc already mentioned we have to make sure that buffers which
are used for DMA are cacheline aligned, otherwise we risk corrupting data
around the buffers.

      USB core: allocate setup_packet using dma_alloc
      USB core: device descriptor using dma_alloc
      USB core: Allocate tmpbuf using dma_alloc
      USB ehci: Use dma coherent buffers for qh/qtd
      USB ehci: put fields of struct qTD directly into struct QH
      USB storage: use dma_alloc where appropriate
      block: use dma_alloc to allocate buffers
      partition: Use dma_alloc for allocating buffers
      USB ehci: rework cache handling
