Merge branch 'samsung/defconfig' into next/defconfig
From Kukjin Kim <kgene.kim@samsung.com>:
It is including new exynos_defconfig for DT configuration of exynos4
and exynos5 together. The old exynos4_defconfig will be used for non-DT
for a while and we will try to move on using exynos_defconfig for only DT.
* samsung/defconfig:
ARM: exynos_defconfig: enable more platforms in defconfig
