Add omap_device pointer to the ARM-specific arch data in the
platform_device.  This will be used to attach OMAP-specific
device-data to the platform device with device lifetime.

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.]

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.

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.

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...
