The existence of irqs.h in mach-davinci/include/mach only makes sense without SPARSE_IRQ as it's then expected to define NR_IRQS and is included from asm/irq.h. As we now support SPARSE_IRQ, this header can be moved to mach-davinci and used as the source of HW interrupt numbers. While updating the includes in various files - also rearrange the headers by directory (linux/asm/mach).
