OK but grrrr!

What needs to happen to the s3c24xx is to get rid of this file.

- Define ARCH_NR_GPIOS in arch/arm/Kconfig entry
  ARCH_NR_GPIO like everyone else

- Get rid of the config symbol NEED_MACH_GPIO_H

-  Move this file down into arch/arm/mach-s3c24xx/s3c24xx-gpio.h
  or whatever and make it local...

I will try to do this myself if noone else helps out, so I'd like to
carry this patch in the GPIO tree provided I can get an ACK from
the S3C24xx maintainer. Tomasz, is that you or Kukjin?

(BTW the above maybe goes for S3c64xx as well .. and S5P
oh well I will get to it.)

Yours,
Linus Walleij
