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

This prevents allocating lv2 page table for the lv1 page table entry
that already has 1MB page mapping. In addition, changed to BUG_ON
instead of returning -EADDRINUSE.

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.

This commit adds device tree support for System MMU.

Prefetch buffer must be handled accurately, exact range of a buffer,
frame by frame manually. Otherwise, it may causes page fault or
deadlock in System MMU.
Thus this patch removes prefetch buffer setting when System MMU is
initialized(enabled).

This patch gates clocks of master H/W as well as clocks of System MMU

This turns on ACGEN and SYSSEL.
ACGEN is architectural clock gating that gates clocks by System MMU
itself if it is not active. Note that ACGEN is different from clock
