[PATCH v2 1/3] rtc: s3c: Remove usage of devm_rtc_device_register()

[Sam Protsenko <semen.protsenko@linaro.org>]

devm_rtc_device_register() is deprecated. Use devm_rtc_allocate_device()
and devm_rtc_register_device() API instead. This change doesn't change
the behavior, but allows for further improvements.
