Allow architecture specific data in struct platform_device V3.
With this patch struct pdev_archdata is added to struct
platform_device, similar to struct dev_archdata in found in
struct device. Useful for architecture code that needs to
keep extra data associated with each platform device.Struct pdev_archdata is different from dev.platform_data, the
convention is that dev.platform_data points to driver-specific
data. It may or may not be required by the driver. The format
of this depends on driver but is the same across architectures.The structure pdev_archdata is a place for architecture specific
data. This data is handled by architecture specific code (for
example runtime PM), and since it is architecture specific it
should _never_ be touched by device driver code. Exactly like
struct dev_archdata but for platform devices.[rjw: This change is for power management mostly and that's why it
goes through the suspend tree.]Signed-off-by: Magnus Damm

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...Signed-off-by: Benjamin Herrenschmidt
