Marek Szyprowski 7171aa2680 iommu/exynos: Workaround FLPD cache flush issues for SYSMMU v5 
[ Upstream commit cd37a296a9 ]

For some unknown reasons, in some cases, FLPD cache invalidation doesn't
work properly with SYSMMU v5 controllers found in Exynos5433 SoCs. This
can be observed by a firmware crash during initialization phase of MFC
video decoder available in the mentioned SoCs when IOMMU support is
enabled. To workaround this issue perform a full TLB/FLPD invalidation
in case of replacing any first level page descriptors in case of SYSMMU v5.

Fixes: 740a01eee9 ("iommu/exynos: Add support for v5 SYSMMU")
