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...
