Subject: iommu/exynos: Remove initconst attribute to avoid potential kernel
 oops
Git-commit: 9d25e3cc83d731ae4eeb017fd07562fde3f80bef
Patch-mainline: v4.14-rc5
References: bsc#975772

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.
