Add the Adreno GPU SMMMUs (MMU-500) for both GPU instances.
Wire up the gpucc clock and power domain on both adreno SMMU nodes in
nord-embedded.dtsi for embedded Nord variants where gpucc is available.

[Severity: Medium]
The commit message states that the gpucc clock and power domain are wired up
in nord-embedded.dtsi for these adreno SMMU nodes.
However, this patch only modifies nord.dtsi and omits the intended changes
to nord-embedded.dtsi. When probing the adreno SMMU on embedded Nord variants
that rely on gpucc, are the clock and power domain properties missing for
adreno_smmu_0 in arch/arm64/boot/dts/qcom/nord.dtsi?
Could this lead to driver probe failures or hardware aborts?

[Severity: Medium]
Similarly, when probing adreno_smmu_1 in arch/arm64/boot/dts/qcom/nord.dtsi,
is this base node also missing the clock and power domain properties that
were intended to be specified in nord-embedded.dtsi?

Oops! The nord-embedded.dtsi changes got lost. Will fix in v3.
