partition to configure sid, so move the check after sid failed.

The DDR memory from 0x88000000 to 0x8FFFFFFF is assigned to M4 on
QM and QXP. The M4 can allocate this memory by two ways,
in SCD or u-boot.
In this patch, u-boot addes the memory reserve node to DTB to pass
the info to kernel, no matter the M4 memory is reserved in SCD
or u-boot. So kernel won't access M4 reserved memory.

Add OP-TEE device tree node for Linux according to args passed from ATF.
If ATF has been built with OP-TEE running, boot_pointer[1] will indicate
that.

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.

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.
