Now there are device tree clocks for the ARM64 SMMU,
add SMMU support to the Stratix10 Device Tree which
includes adding the SMMU node and adding IOMMU stream
ids to the SMMU peripherals.

Currently the clocks are specified in a structure as well as
in the device tree. Since all the information about clocks can be
pulled from the device tree, parse the device tree for the clock
information if specified.

This patch series adds SMMU support to the SOCFPGA Stratix10 family
of parts. The addition of a clock parameter was required to ungate
the SMMU clock.

I'm enabling the ARM SMMU-500 on an ARM64 A53. I'm hitting a data abort

Linux starts in EL2 mode but drops down to EL1 mode by the time it
