[ARM] 3557/1: S3C24XX: centralise and cleanup uart registration
Patch from Ben Dooks All the S3C24XX based devices currently have similar uart blocks, in the same location. Make the process of adding new uart blocks easier by commonising the device definitions and adding a new init function for the cpu code.
