This patch makes the EHCI driver work on ARM platforms which usually do not support automatic cache snooping. It uses the new DMA memory mechanism (which needs to be correctly set up in the Coreboot mainboard code) to allocate all EHCI-internal communication structures in cache-coherent memory, and cleans/invalidates the externally supplied transfer buffers in Bulk and Control functions with explicit calls as necessary. BUG=chrome-os-partner:21969 TEST=Make sure booting from the EHCI port now works without any additional tweaks.
