This adds the support to turn on the regulators required
for SMMUs. It is turned on during the SMMU probe and remains
'on' till the device exists.

This series adds support for xlate callback to add master
devices configs using generic bindings and clocks/regulators
required to access smmu.
OF_IOMMU_DECLARE is used to register and probe the smmu controller
devices before the masters are added in of_platform_populate.
Here, we are registering
This adds of_xlate callback to arm-smmu driver. xlate callback
is called during device registration from DT for those master
devices attached to iommus using generic iommu bindings.

1 file changed,
This patch uses IOMMU_OF_DECLARE to register the driver
and the iommu_ops. So when master devices of the iommu are
registered, of_xlate callback can be used to add the master
configurations to the smmu driver.

On some platforms with tight power constraints it is polite to only
leave your clocks on for as long as you absolutely need them. Currently
we assume that all clocks necessary for SMMU register access are always
on.
Add some optional device tree properties to specify any
