Samsung touchscreen updates

[Ben Dooks]

Dimitry, this is a set of updates for the Samsung platform support for
touchscreen devices and the drivers/input/touchscreen items for the
s3c2410_ts driver.

Since the changes have some interedependency, I would like permission
to merge this via the Samsung platform tree with your acknowledgement
for the drivers/input/touchscreen items.

The arch/arm/* portions of this patchset have been included as FYI and
to show other interested parties what is goign on.

Please let me know what you think.
