Since struct platform_device now has the ability to pass resources,
defined by the platform to the device driver, we can now use this
to handle platform specific devices.  One such instance is the
StrongARM SA1111 companion chip, which can appear in various address
spaces, and connected to different IRQ lines depending on how many
cups of coffee the hardware designer had, the direction of the wind
outside the designers office that day.

We also convert some of the other StrongARM peripheral on-chip
devices to use struct platform_device.

ARM also provides a platform_add_devices() function which can be
used by platform code to bulk-register a tabular set of platform
devices.
