Subject: [PATCH] arm64: dts: Fix rtc by providing rtc_src clock

Add rtc source clock as exynos7 needs source (32.768KHz) clock
for rtc block. Without this currently rtc driver probe is broken
on this SoC, thats because rtc-s3c driver expect rtc_src clock to
be provided for _s3c6410-rtc_ type rtc controllers.
