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
