The global irq_desc array is soon going to be accessible only with
!CONFIG_SPARSE_IRQ. We should start using the generic irq_to_desc()
routines instead.

- Move it into a separate file; clean and streamline it
- Restructure the init code for reuse during secondary dispatch
- Support both levels (primary, secondary) of IRQ dispatch
- Use a workqueue for irq mask/unmask and trigger configuration
Code for two subchips currently share that secondary handler code.
One is the power subchip; its IRQs are now handled by this core,
courtesy of this patch. The other is the GPIO module, which will
be supported through a later patch.
There are also minor changes to the header file, mostly related
to GPIO support; nothing yet in mainline cares about those. A
few references to OMAP-specific symbols are disabled; when they
can all be removed, the TWL4030 support ceases being OMAP-specific.
