Add s3c64xx support to touchscreen driver

Hi,

these patches add support for the s3c64xx platforms to the touchscreen driver. This was based on next-samsung in Ben Dook's tree.

These depend on:
[PATCH] ARM: SAMSUNG: Fix null pointer dereference in ADC driver

I'm not quite sure regarding the resources in patch 3, perhaps these should be somehow shared with the ADC driver? (I also can't seem to figure out how the s3c24xx handles this at the moment..)

Regards,

should be in for-rmk/samsung3

I'll try and give this some thought, however we're in the middle of some reworks in this area and it might take time to think about it.
