drivers/rtc/rtc-s3c.c: add .needs_src_clk to s3c6410 RTC data
[ Upstream commit 8792f7772f4f40ffc68bad5f28311205584b734d ] Commit df9e26d093d3 ("rtc: s3c: add support for RTC of Exynos3250 SoC") added an "rtc_src" DT property to specify the clock used as a source to the S3C real-time clock. Not all SoCs needs this so commit eaf3a659086e ("drivers/rtc/rtc-s3c.c: fix initialization failure without rtc source clock") changed to check the struct s3c_rtc_data .needs_src_clk to conditionally grab the clock. But that commit didn't update the data for each IP version so the RTC broke on the boards that needs a source clock. This is the case of at least Exynos5250 and Exynos5440 which uses the s3c6410 RTC IP block. This commit fixes the S3C rtc on the Exynos5250 Snow and Exynos5420 Peach Pit and Pi Chromebooks.
