ARM: S3C24XX: Add extended GPIO used on S3C2443 and beyond
Add the GPIO banks that are used on the S3C2443 and above to the
list of available GPIOS.
Currently we do not have any limit on the SoC GPIO, so these are
being registered whether the SoC has them or not. It is currently
up to the user not to try and use them.
