[PATCH] GPIO API: S3C2410 wrapper cleanup
this one adds an #include <asm/arch/regs-gpio.h>.
Tested by Roman Moravcik on s3c2440.
Based on the discussion last december
(http://lkml.org/lkml/2006/12/20/243), this patch
- fixes comment and includes in gpio.h
- adds the gpio_to_irq definition for S3C2400
- includes asm/arch/regs-gpio.h for pin direction
