dt-bindings: arm-smmu: Document SM61[12]5 GPU SMMU

Browse source

Both of these SoCs have a Qualcomm MMU500 implementation of SMMU
in front of their GPUs that expect 3 clocks. Both of them also have
an APPS SMMU that expects no clocks. Remove qcom,sm61[12]5-smmu-500
from the "no clocks" list (intentionally 'breaking' the schema checks
of APPS SMMU, as now it *can* accept clocks - with the current
structure of this file it would have taken a wastefully-long time to
sort this out properly..) and add necessary yaml to describe the
clocks required by the GPU SMMUs.
