[PATCH 09/13] ARM: dts: exynos: Use S5M8767 clock in S3C RTC in Exynos5250 Spring

[Krzysztof Kozlowski <krzk@xxxxxxxxxx>]

Use the 32 kHz clock from S5M8767 PMIC in the S3C RTC node. Except
making the S3C RTC working, this also fixes dtbs_check warnings:

  arch/arm/boot/dts/exynos5250-spring.dt.yaml: rtc@101e0000: clocks: [[2, 337]] is too short
  arch/arm/boot/dts/exynos5250-spring.dt.yaml: rtc@101e0000: clock-names: ['rtc'] is too short
