[RESEND PATCHv2 4/5] rtc: s3c: Add support for RTC of Exynos3250 SoC

This patch add support for RTC of Exynos3250 SoC. The Exynos3250 needs source clock(32.768KHz) for RTC block. If source clock of RTC is registerd on clock list of common clk framework, Exynos RTC drvier have to control this clock. Clock list for s3c-rtc device: - rtc : CLK_RTC of CLK_GATE_IP_PERIR
