[PATCH v1] drivers: meson: secure-pwrc: always enable DMA domain

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.

I'm not entirely sure if this domain should always be enabled on or it
should be separately enabled in dts file. Comments are welcome.
