The s3c24xx_init_irq function that was the base for all irq inits is now only used to initialize the real s3c2410 irqs. Therefore rename it and also move its declaration from plat/cpu.h to common.h The eint declaration is used by the vast majority of the SoCs and gets therefore placed outside any ifdefs.
