By the look of it, omap_hwmod_irq_info serves multiple purposes:
- low level configuration (pads, probably more stuff)
- interrupt description for some drivers, using resources.

It should be fairly easy to do the latter, but the former looks more
tricky (it would push the pad configuration down to the drivers, which
is avoided at the moment).

Probably there is a workable strategy, but my knowledge about OMAP is
close to *nothing*...
