[ARM] 3613/1: S3C2410: Add sysdev and sysclass

Browse Source 
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.
