s3c-mci driver for testing

Hi Roman,

I tested it with rx1950.
This driver needs proper cpu selection at first. My s3c2442 was
detected as s3c2410 with s3cmci_probe_2410(..). At second the code
seems buggy because driver cause massive data loss.
..
s3c2410-sdi s3c2410-sdi: running at 16463kHz (requested: 20000kHz).
