Adding platform devices dynamically is definitely the right way forward
for new platforms, as Greg explained recently. The imx_add_platform_device()
function you have defined looks useful for this, and I guess it could
be added globally, next to the existing platform_device_register_resndata,
platform_device_register_data and platform_device_register_simple functions
that we already have doing similar things.

I'm not convinced that the various wrappers you have on imx are the
best solution, though I have not come up with anything better either ;-)

This will also get a lot easier once we have the ability to define
devices in using dtc, because that takes care of the resources.
