iommu/exynos: Remove initconst attribute to avoid potential kernel oops
commit 9d25e3cc83d731ae4eeb017fd07562fde3f80bef upstream. Exynos SYSMMU registers standard platform device with sysmmu_of_match table, what means that this table is accessed every time a new platform device is registered in a system. This might happen also after the boot, so the table must not be attributed as initconst to avoid potential kernel oops caused by access to freed memory.
