[ARM] S3C64XX: Add generic s3c64xx sys device.
Add an s3c64xx_sysclass and device for items that currently want to bind to any s3c64xx processor. The first user of this will be parts of the s3c64xx suspend support which need to save device state over suspend/resume. Signed-off-by: Ben Dooks <ben-linux@fluff.org>
