[V4,2/4] ARM: dts: exynos: change status property of dwmmc nodes

Commit Message

Yuvaraj CD Sept. 3, 2013, 6:04 a.m. UTC

According to ePAPR, chapter 2.3.4, the status property has
defined that it should be set to "disabled" when "the device
is not presently operational, but it might become operational
in the future".

So this patch disable dwmmc node by "status = disabled" in SOC
dts file and enable dwmmc node by "status = okay" in board specific
dts file.
