Hyungwon Hwang cdbfca8907 drm/exynos: fix the initialization order in FIMD 
Since commit 0f04cf8df0 ("drm/exynos:
fix wrong pipe calculation for crtc"), fimd_clear_channel() can be
called when is_drm_iommu_supported() returns true. In this case,
the kernel is going to be panicked because crtc is not set yet.
