* Makefile.am, configure.ac, preinstall.am, s3c2400/include/s3c2400.h:
Add CPU type s3c2410. Add a new s3c24xx common file shared between
s3c2400 and s3c2410. Most content is moved from s3c2400 now. Some
were changed to include <s3c24xx.h> instead of <s3c2400.h>.
* s3c2410/include/s3c2410.h, s3c2410/irq/bsp_irq_asm.S,
s3c2410/irq/irq.h, s3c24xx/clock/clockdrv.c, s3c24xx/clock/support.c,
s3c24xx/include/s3c24xx.h, s3c24xx/irq/bsp_irq_init.c,
s3c24xx/irq/irq.c, s3c24xx/irq/irq.h, s3c24xx/timer/timer.c: New files.
