OMAP INTC irqchip driver will be moved under drivers/irqchip/ soon but we still have a dependency with mach-omap2 when it comes to idle functions. In order to make it easy to share those function prototypes with OMAP PM code, we introduce this new header. To avoid modifying several board-files and some of the PM-related code, we just include the new header from common.h which was already included by all users of IRQ-related PM code.
