[patch 19/42] s3cmci: update probe to use new platform id list

[patch 19/42] s3cmci: update probe to use new platform id list

[akpm]

From: Ben Dooks <ben@simtec.co.uk>

Use the platform id list to match the three different versions of the
hardware block that this driver supports.

This will change the prefix of the console messages produced by this
driver to be prefixed by s3c-mci instead of the hardware block name, such
as s3c2440-mci.
