mfd: twl4030 IRQ handling update
- 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.
