platform data for the s3c-adc or hardcoded delay?

We had this for the touchscreen but it doesn't make sense now that the
driver has been converted to use the s3c-adc API.

const static struct s3c_ts_platdata gta02_ts_cfg = {
? ? ? .delay = 10000,
? ? ? .presc = 0xff, /* Slow as we can go. */
};

Without this delay the TS doesn't work for us:

Now I see two options:

1) Hardcode the delay in plat-s3c24xx/adc.c (As it's done in [1]).
2) Submit patches adding s3c_adc_platdata.

I would rather go for a platdata. I do believe that prescaler and delay
are machine specifics.
