ARM: exynos: add missing of_node_put for loop iteration

[ Upstream commit 48d551bf20858240f38a0276be3016ff379918ac ]

Early exits from for_each_compatible_node() should decrement the
node reference counter.  Reported by Coccinelle:

  arch/arm/mach-exynos/exynos.c:52:1-25: WARNING:
    Function "for_each_compatible_node" should have of_node_put() before break around line 58.
