I still don't understand why this particular MFD subnode needs a reg and not
the other ones, using reg would need adding #address-cells/#size-cells on top
node and change all examples/DT for nothing.

Like the other meson-gx-hhi-sysctrl subnodes, it's a register bit soup and this
one is no exception.
