Looks good to me, but how about cleanup useless definitions together like
following?

Actually, S3C2410_RTCCON_CLKSEL, S3C64XX_RTCCON_TICMSK,
S3C64XX_RTCCON_TICSHT, S3C2410_RTCALM_ALL, S3C2410_RTCRST and S3C2410_RTCDAY
are not used.

And I'm not sure we really need to define the S3C2410_RTCREG(x), but this
can be sorted out next time with similar others.

Thanks.

Best regards,
Kgene.
