drivers: meson: secure-pwrc: always enable DMA domain
[ 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.
