This sets CONFIG_SYS_HZ to 1000 for all boards that use the s3c2400 and s3c2410 cpu's.
Tested on an Embest SBC2440-II Board with local u-boot patches as I don't have any s3c2400 or s3c2410 boards but need this patch applying before I can submit patches for thge SBC2440-II Board.
Also, ran MAKEALL for all ARM9 targets and no new warnings or errors were found.
Note that the existing code modified by this patch does not meet the u-boot coding style but I'd like to handle this separately and submit patches to fix this later.
It look fine but it will be good that someone test it on the other soc I'll try to ping someone
