feat(tc): add SCMI power domain and IOMMU toggles
Compile-time controls have been added for the following:
* SCMI power domain use for DPU and GPU.
* SMMU-700: planned rework required to use IOMMU correctly
for DPU and GPU.
These will allow easier experimentation in the future without
ad-hoc changes needed in the dts file for any sort of analysis
that requires testing different paths.
For TC3 however, the DPU is in an always on power domain so SCMI power
domains are not supported.
