Please, remove all theses #ifdef. I don't see the point of them as it's
only few lines of C code and they don't get executed when running on
other platforms than 2410.
The problem is that s3c2410_gpio_cfgpin() and S3C2410_* isn't defined
on S3C64XX builds so this gives implicit declaration errors.
hmm... I didn't look in details but I thought such kind of issues was
going to be fixed thanks to the changes in Ben's -next-* branches.

Hmm I checked next-samsung but didn't see anything relevant..
Normally I check Ben's tree pretty regularly (this diff was based on an older next-samsung), so if he changes something I should pickup.

I can remove one pair of #ifdef's though, if I move the first one inside s3c2410_ts_connect() there's no need for the second one.
