[PATCH] I2C: add w83627hf driver

The following patch against kernel 2.6.3 adds the w83627hf driver,
I have ported from the 2.4 version.

Jean Delvare has asked me to send this patch to you for applying.
I have tested it on w83627thf. Mark Hoffman has reviewed the code
and has also tested it on w83627thf.
