i2c speed up

I found the reason why the i2c is on the phone so slow.
The phone uses the driver i2c-s3c2410.c
And after each acces to i2c there is the function msleep(1).
Which needs on the openmoko about 10ms.
I made a little patch for that and now i2c is quite fast.
Maybe that should help someone. One I2C-Access needs now about ~0.6ms
and before it was 10ms.
I attached the patch.
