Driver core: add dev_archdata to struct device Add arch specific dev_archdata to struct device Adds an arch specific struct dev_arch to struct device. This enables architecture to add specific fields to every device in the system, like DMA operation pointers, NUMA node ID, firmware specific data, etc...

[ARM] Add a reference from struct device to the dma bounce info dmabounce keeps a per-device structure, and finds the correct structure by walking a list. Since architectures can now add fields to struct device, we can attach this structure direct to the struct device, thereby eliminating the code to search the list.
