[ARM] 3613/1: S3C2410: Add sysdev and sysclass
Patch from Ben Dooks The S3C2440 and S3C2442 both have their own sysdev and sysclass for differentiating them from the currently default S3C2410. Add a sysdev for the S3C2410 as part of the work to make the code be non-dependant on the S3C2410. Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
