The main aim for this cycle is to have the u8540 booting to a
console. However, the u8540 doesn't support all of the u8500
platform devices yet. After this stage is complete we can then
fill in the inadequacies, such as specific clock support at a
later date. To achieve this we're placing devices supported by
all platforms into a common device structure and the remaining
ones into a platform specific one.
