ARM: S3C24XX: modify s3c2416 irq init to initialize all irqs
Previously the irq init used s3c24xx_init_irq and an additional arch_initcall to add the cpu specific irqs. To be able to simplyfy the irq init later, create a new function s3c416_init_irq, which then calls s3c24xx_init_irq but also adds the cpu specific irqs.
