Add OP-TEE device tree node for Linux according to args passed from ATF.

that.

01cacf9682 imx8: fdt: configure sid for masters
On i.MX8QM, sid is programmable, so we could program sid according the
value encoded in device tree.

This patch support legacy bindings which are still being used by XEN
and new bindings used by Linux Kernel.

9f779fa410 imx8: disable node when the resource is not owned
When resource is not assigned to non-secure Linux, if linux continue
to use the node, linux may crash or hang. So need to set the node
status to disabled for not owned resources.

The resource id is in the power-domains property in device tree,
so parse the power-domains property to get the resource id and
use scfw api to check whether it is owned by current partition.
