MLK-18036-1 Add "fsl,optee-lpm-sram" node for optee os power management.
This node will be used by the OCRAM driver in optee to:
* Get the OCRAM start address for power management in optee.
* Add an entry that will overwrite ocrams nodes and dynamically reduce
the OCRAM available for mmio-sram in Linux.
That way we do not touch the legacy Linux boot and remove the dedicated
optee device tree.
