Ben Dooks 1635ca4aaf ARM: S3C24XX: Remove macros mapping GPIO number to base
As part of the cleanup, remove the old macros mapping GPIO numbers
to the base of the register now we have gpiolib to manage the GPIO
mappings for us.

Ben Dooks 2c8fcfbf73 ARM: S3C24XX: Start cleanup of GPIO numbering
Start cleaning up the numbering of GPIO banks by removing the old
bank start definitions currently being used by some of the header
files.

Ben Dooks 7ced5eab39 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.

Ben Dooks 070276d5d0 [ARM] S3C24XX: GPIO: Change to macros for GPIO numbering
Prepare to remove the large number of S3C2410_GPxn defines
by moving to S3C2410_GPx(n) in arch/arm.

The following perl was used to change the files:

    perl -pi~ -e 's/S3C2410_GP([A-Z])([0-9]+)([^_^0-9])/S3C2410_GP\1\(\2\)\3/g'

Ben Dooks 75cbcff372 [ARM] S3C24XX: GPIO: Add S3C64XX style GPIO numbering
Move the new style of GPIO numbering by using a single
macro for each GPIO bank. This means S3C2410_GPA0 becomes
S3C2410_GPA(0), and so on.

Ben Dooks 67c2addcb0 [ARM] S3C24XX: Add S3C_GPIO_END definition
Add the definition for S3C_GPIO_END to allow the PM code to build.

This means moving the GPIO bank numbers to a separate file to allow
the gpio and regs-gpio to include them. Including regs-gpio.h into
gpio.h causes too many build problems and adding gpio.h would mean
editing a large number of files.
