driver core: Add ability for arch code to setup pdev_archdata
On some architectures we need to setup pdev_archdata before we add the device. Waiting til a bus_notifier is too late since we might need the pdev_archdata in the bus notifier. One example is setting up of dma_mask pointers such that it can be used in a bus_notifier. We add weak noop version of arch_setup_pdev_archdata() and allow the arch code to override with access the full definitions of struct device, struct platform_device, and struct pdev_archdata.
