Subject: [PATCH v2 1/1] ARM: dts: Add mclk entry for Snow and Peach Pit/Pi boards

From: Tushar Behera <tushar.b@...sung.com>

On Snow, Peach Pit and Peach Pi boards, the Exynos SoC XCLKOUT output pin
provides the master clock (mclk) to codecs. So make them a clock consumer.

Changes since v1:
 - Rebased on top of Kukjin's for-next branch since v1 made on top of
   3.19-rc7 doesn't apply cleanly on that branch. Sorry for the noise.
