[PATCH] RTC: class driver for Samsung S3C series SoC

This is a renamed and tested version of the previous S3C24XX RTC class
driver.

The driver has been renamed from the original s3c2410-rtc, which is now too
narrow for the range of devices supported.

The rtc-s3c has been chosen as there is the distinct possibility of this
driver being carried forward into newer Samsung SoC silicon.
