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.

Please drop this patch since I took it from [0] but that patch was when
the master clock was grabbed in the ASoC machine driver but the final
version that got merged grabs the master clock in the codec driver so
it has to be in the codec device node too.

I'll send the correct version soon.

Best regards,
Javier
