[PATCH 08/13] ARM: dts: exynos: Add max77686 clocks for S3C RTC in SMDK5250

[Krzysztof Kozlowski]

Add clock-cells to max77686 PMIC node so its 32 kHz clocks could be used
later in the S3C RTC node. Except making the S3C RTC working, this also
fixes dtbs_check warnings:

  arch/arm/boot/dts/exynos5250-smdk5250.dt.yaml: rtc at 101e0000: clocks: [[2, 337]] is too short
  arch/arm/boot/dts/exynos5250-smdk5250.dt.yaml: rtc at 101e0000: clock-names: ['rtc'] is too short
