arm64: dts: imx8ulp: add secure enclave node
Add the EdgeLock Enclave (ELE) secure-enclave node to the i.MX8ULP SoC dtsi, together with a label for sram@2201f000 that the node references. Keep the node disabled in the SoC dtsi so it does not impose a reserved-memory requirement on every board. Boards enable the enclave and provide its memory-region by including imx8ulp-firmware.dtsi.
