rtc: s3c: Document in binding that only s3c6410 needs a src clk
The S3C binding doc says that the RTC and RTC source clocks are required but the S3C driver supports different HW IP and only the s3c6410 needs a source clock. Fix the binding explaining that the source clock is only needed for the s3c6410-rtc compatible controller.
