[ Upstream commit 0bb4644d583789c97e74d3e3047189f0c59c4742 ]
Starting from commit e45f243409db ("firmware: meson_sm: populate platform devices from sm device tree data") pwrc is probed successfully and disables unused pwr domains. By A1 SoC family design, any TEE requires DMA pwr domain always enabled.
