iommu/tegra-smmu: Move flush_dcache to tegra-smmu.c
Drivers should not be using __cpuc_* functions nor outer_cache_flush()
directly. This change partly cleans up tegra-smmu.c.
The only difference between cache handling of the tegra variants is
Denver, which omits the call to outer_cache_flush(). This is due to
Denver being an ARM64 CPU, and the ARM64 architecture does not provide
this function. (This, in itself, is a good reason why these should not
be used.)
