[PATCH 2/3] ARM: S5P: Add initial map for GPIO2 and GPIO3

[Kyungmin Park]

NAK.

This approach don't make a common GPIO framework. I already send the
common GPIO framework which send the base address to GPIO framework
and handle it regradless GPIO is one or three.

http://lists.infradead.org/pipermail/linux-arm-kernel/2010-August/022513.html

With this patch, we can use the common GPIO framework and remove the
VA_GPIO dependency.

Thank you,
Kyungmin Park
