ARM: dts: Fix wrong clock binding for sysmmu_fimd1_1 on exynos5420
The sysmmu_fimd1_1 should bind the clock CLK_SMMU_FIMD1M1, not the clock
CLK_SMMU_FIMD1M0. CLK_SMMU_FIMD1M0 is a clock for the sysmmu_fimd1_0.
This wrong clock binding causes the problem that is blocked in iommu_map
function when IOMMU is enabled and exynos-drm driver tries to allocate
buffer via DMA mapping API on Odroid-XU3 board.
