This commit adds cache flush for removed small and large page entries
in exynos_iommu_unmap(). Missing cache flush of removed page table
entries can cause missing page fault interrupt when a master IP
accesses an unmapped area.

Commit 25e9d28d92 (ARM: EXYNOS: remove system mmu initialization from
exynos tree) removed arch/arm/mach-exynos/mach/sysmmu.h header without
removing remaining use of it from exynos-iommu driver, thus causing a
compilation error.
This patch fixes the error by removing respective include line
from
The current exynos-iommu(System MMU) driver does not work autonomously
since it is lack of support for power management of peripheral blocks.
For example, MFC device driver must ensure that its System MMU is disabled
before MFC block is power-down not to invalidate IOTLB in the System MMU
when I/O

Will plan to merge into cifs-2..6.git soon.
Probably should also go to stable kernels

It makes more sense to enter a bitmask in hexadecimal rather than
decimal. Sadly we can't make it read back as hexadecimal.
